Piston chamber cc'S, and piston top volume, I also need. You have to be sure on the deck height. Head gasket sounds right.
Denny,I think his chamber volume is off.
His heads should have a combustion chamber volume of around 64 cc if the have not been surfaced to much or milled.
The 79 cc's seem's a little large to me.
