My choice of heads would starting with what I feel are best would be 461 or 462 double hump Heads both are 64cc, next would be 186 powerpack heads also 64cc, next 414 Z-28, corvette, LT-1 64cc heads, another good 64cc casting are 040 and 041 heads. The 882 casting is just a 76cc with 1.94 intake & 1.5 exhaust, and to my kwowledge you cant put an 2.02 & 1.6 valves in them. If your going to use 76cc heads look for 487 or 487x casting at least with them you can put the 2.02 & 1.6 valves in them.

Is there a specific head number rule. Like in IMCA. If not if you use four valve relief pistons with the thickest head gasket you can find with 64cc heads 462's or 461's preferably that will put you at 9.2 to 1. If you have an Imca rule I would say 441's

It is IMCA and have to keep it at 9:1 max. I have a set of 882s and 487s. Just wasnt sure what differences each set had. Thanks
