Rotary Valve head for grey motor

[87 velo]

Had heard that we had one of these at work so I went looking, took a couple of months to find, but here it is.  This one is off a hydroplane, I'd say 90% of it is there, but there is a piece missing that goes between the rotary valve and the head missing, will try and assemble when time permits.  Still have the induction system it has 6 Amal (motorcycle) carbs attached. A nice piece of Aussie ingenuity

Hi mate I was wondering if you still had the head lying around I'm a bit of a backyard machinist and I'm looking for a new project And I have always wanted to replicate one of these heads and test it on a motor and see what I can do with it

So my question is would you be able to get some measurements off the head or sell me the head so that I can get all of the measurements off it myself and make a replica

I need the measurements for the internals, the intake and exhaust ports. Basically any of the measurements that I can get off the engine block

Cheers jordyn :)

Dunstans nephew runs a mechanic / dyno shop here in Adelaide (Kent Town), he has a rotary head in his workshop, last time I was there he was still restoring it. I will try and find my photo's.
