Hiya Smithy,
yep, I'm using a Black 12 port head from a VK crummydore. The reason I was asking about the need for a hole between pot 1 and 2, is that I have heard so many different stories. I even read somewhere on the net that you only have to drill 3 holes. I guess that 3 holes may also work, but wanted to use the most common meathod just to be sure.
I pulled the head from an old red motor lat night and did the gasket comparison thing that you suggested, and worked out that the 4 outer holes in the block,(the ones that get blocked off), don't have the material on the head to support the full hole. I am going to drill and tap 3/8 BSPT threads and use a socket head water plug (tapered). This will sit just slightly below the surface of the block, so that the water pressure from the block doesent even get to the gasket.
As far as the ECU goes, I will just be using the standard Bosh unit. Maybe later I will play with a more advanced tunable unit, but for now I just want to get the conversion done with minimum hassles as I drive the car daily. (luckily I have a borrowed car for next week).
The most difficult thing about the whole conversion will be hooking up a cable to operate my 2 Speed powerglide transmission. (you may have seen my post).
Should have some news in a week or so, I'll let you know how it all goes.
Cheers, Damon.
