FE-FC Holden Discussion Forum

i have a stage 2 yella terra head for a 202 that i picked up for a song and was wondering a few things

a) what are they worth new?
b) anyone had any experience with them? are they good?
c) what's a good cam profile to match? i was thinking a 25/65.

cheers.

Aaron
        How could you have picked it up for a song, if you need to ask what are they worth now. ???
You also ask if they are good and what size cam would go with it, that depends on what else you are planning to do to your motor. All three of your question have the same answer, that is How long is a piece of string. ;D Tell us what else you had planed for the motor, if you are going for a manual or auto what your diff ratio is and what you want your car to do when finished. Now that you have the head you just need to build the car around it. ;D

huh? sorry, but i have no idea what they are worth and it was given to me for the cost of a carton of VB.

are you saying that is too much to pay? ???

the car is a daily and on gas and is a stock-but-rebuilt trimatic auto.

after some research last night i decided on the wade 1166a cam which is approx a 20/60 but with 400thou+ of lift - almost double valve spring territory.

i have a blue bottom end - linished, polished and cryo treated with ARP studs. i'm using ACL HQ racing pistons with moly rings and trimetal and a VK elec dizzy.

water and oil galleries in the block have been sleeved proud of the block and the head galleries recessed to take said sleeves so i can use a very thin copper head gasket without any bypass worries. also has an ARP head stud kit on it too.

i have a pair of turbos sitting in the shed i might stick on it too, but with the 10.0:1 CR i think water injection might be the go with only low boost - just to improve swirl.

so yes, that is the car as it stands - minus a head.

Is it for an engine for your FE/FC??

Be careful that water galleries line up when using a red head on a blue block, but from your description of your block, you would know something so basic.  

sorry - my bad.  ::)

blue crank and rods in a red block  - you know when you're trying to explain something and you know what you mean but it's so easy to overlook something in the explanation because it's so obvious to you...?

ah...yeah... :-[

anyways, what are the heads worth new? are they good or should i just build a decent red head instead?

and yeah, it's for my FC station sedan.

Sorry Sarge.....but that sounds like you were just told ! ( In a jovial way - lol ).

Sounds like Aaron knows a bit, which is probalby more than I know. ...but for what it's worth Aaron, from my research, you can't buy a new YT Head for a Red motor even if you wanted too.  There have been many threads about this and even after the idea of a petition attached to a bulk order of heads, YT were still not interested ( from memory. )

I think you can get the heads for the Blue Black Motors because yes they are different.

To get stage 2 - 3 ( just an indication ), you would have been looking at around the grand mark easy.

I know of such a head....it is an Original Stage 2-3 YT head ( NOT a YT recond Holden unit as they used to sell ), but a full on YT creation.   It is a bare head ( no springs, valves ect ) and is still wrapped in plastic and he was chasing $1000 !  ( Not sure if he still has it  ).

YT used to make NEW heads, and they also used to take Holden Iron heads and recon them to YT specs..paint them yellow ( not always the case though ), and sell them for less than a NEWIE !

I'm no guru on the subject, but have done enough asking around when I was doing up my 202.

As it turned out, when I took my head to the Head Reconditioners, they found it to be a YT creation anyway ( The recon Holden type though ).....so all it cost me was $450 for a recond and new stainless seats for unleaded and I was set !

Hope this answers some of your questions.

Cheers

Mark

yes it answers my question - thanks very much for that Mark  ;D

but now i have to chase down a blue block and swap everything over! ::)

shouldn't be hard, just a pain the proverbial to have to rebuild the whole thing again and have the water galleries and oil galleries studded again.

i guess i can kiss the next month of spare time goodbye!

i'm glad my pistons are a +60thou size though, coz i doubt there's any chance of finding a virgin block anymore!

i'm basically weighing up if it's worth doing a red head to almost race spec or using this yellaterra. i guess i've already got the head though, and it's only a block swap (short engine is still on the engine stand) so i should prob run with that.

cheers for your help.  8)

Aaron,

I'm not sure why you need to change your block?

We have a YT head on a red and it works fine???

just use the YT head IMO, unless you're chasing more HP.

they already have bigger valves and exhaust ports.

not sure on exact specs or anything, this is just from casual observation.

Cheers

Ed

okay i'm way confused now.

so the water galleries aren't the same for a red and a blue - and the YT head is designed for a blue or black - but you have one on a red working fine...?

are they only out by a few mm's or something?

??? ??? ???

and yeah Ed, eventually i'll chasing more HP but it'll be with turbos so any flow figures will go straight out the window anyway ;)

Aaron

- why are you stuffing around so much over a head that was cheap.  Dump the lot and go a V8 and turbo or supercharge it if you are really after power and just having us on!!

I think the thrust is that you can still get new/recond YT heads for blue/black motors, but YT don't do the red variant any more.

Since your beer-priced job (bargain price BTW - has he got any more?) is old stock, it could be either.  However, by the sounds of your block it's not going to be hard to check...

Hope that helps,
RET

i'm stuffing around with it coz it was practically free and has less than 500ks on it.

i guess i'll just have to wait and see what block it's for when it arrives.

earlee - the bottom end is built and owes me money so i want to use it. no V8s for this baby - there's just something way cooler about keeping it a sixpot. a V8 just requires SO MUCH more work.

with the high CR pistons and smaller combustion chamber it should be a perfect combo for gas.

and RET - actually i DO have another head in same condition but with a few more kays on it. but that one cost me money and needs a bit of a clean up. no welds or anything though, just a bit of a clean. prob a good weekend just double chacking everything, but i can't be arsed and when i was offered this head for a carton i thought "bewdy! that saved a weekends work"

still, for a couple (or more) of the folding greenies i'd probably let it go.

so for final clarification, YT USED to make them for red, blue and black, now only make them for blue and black (which fit a red block with a bit of pissing about) and the old-er stock could be any of the three.

there's hope for my precious spare time yet.

That's about the size of it, although I think there's only two types: red and black/blue.

Folding greenies?  I could probably dredge up a few old $2 notes.  15 of them would equate to a carton of VB, more or less? ;D

I'm not really in the market, but your approximate location would be most helpful if you are selling.  You'll be deeply unpopular with your postie if you drop that in a post-box.  Australia Post get a bit funny about sending engine heads (and other kinds of heads too :o) through the mail.

cheers
RET

lol yeah a carton... ::) ;D

i'll fill in my location too.

one of my friends uses greyhound bus freight to move things across the country - cost him $15 for a bench seat to go from QLD to melbourne, $30 to get a whole 4cyl engine block (lotus escort - worth $$$) from darwin to QLD and $30 to get another head to me here in WA.

much cheaper and far more reliable that aus post.

Aaron
        A carton of VB is the perfect price. When your bargain arrives on the valve check if the letters YT are there. YT no longer make Red 6 cylinder heads but still do for the black/blue, as stated in other posts here. I have been told that there is a alloy head being make for red blocks too YT spec's but it's not cheap around $2500 But have not heard anymore about them. The 186 I am making for my wagon has a 12 port blue head and you should be able to fit your head to your block, I was told just make sure I use a cooper gasket. The people I spoke to about my block & motor where freeflow www.freeflowcylinderheads.com.au maybe give them a call. They are into V8 heads but helped me out heaps when it came to what head to use and what spec's I need the head to be.

The YT red heads go on ebay for anything between $200 (if you are lucky) and $1000 (a brand new one just ended for $850...see

Sarge,

When you metioned to check for YT on the bottom of the valves what was your point?

My YT head has YT on the bottom of the valves but when I had it reconditioned they were not replaced with ones with YT on them - I didn't ask why.  Are large red motor valves not available from YT anymore?

Dave

see, that's what i was told too re: the copper head gasket.

and if the YT heads are worth that much then i think i'll just run with that. saves having to spend more money then - i can get similar performance for a whole lotta nuthin'!

what did you have to modifiy to get the blue head to fit the red block? are all blue heads 12 port? i thought only black heads were 12 port... ???

edit: i've just read up about drilling and tapping some water jackets in the block and plugging them off with grub screws to make the 12port head fit.

awesome - looks like i'm on my way. 8)

thanks to everyone for their help. it's so nice to be helped when you're a newbie and not sh1tcanned because you have a few genuine questions.

next round is on me... ;D
