Thanks for all the compliments guys but it was Bruce's idea, I just took it and ran with it.

I'd like to update this with more info on older aftermarket heads if possible. If you have any old heads, not in the charts, please carefully measure the combustion chamber cc''s. This can fairly easily be done with a spare head gasket, a $0.20 3 cc syringe from a drugstore and a piece of clear Lexan with head bolt holes drilled in it and a small hole near the top of the valve pockets. I know there were a bunch of aftermarket heads produced by the Aussies and others.
