Got a 1986 350 and in order to run the pistons that i got without running race fuel i have to have either 64cc head with 10.9:1 or 76cc heads with 9.5:1. I have two sets of heads but im not sure how to check the cc of them. Any help would be appreciated. :D Thanks

Take tho a shop and have them CC'd or buy a CCing kit if you need to know exactly.

It would be cheaper just to look them up by their casting numbers, especially if they are GM heads you dont want to waist any more money than you have to on crappie heads.

If anyone out there wants to CC their heads for cheap - do the plexiglass or glass plate with a hole trick - and instead of buying a burrette, go to a vet supply or equivilent and get a big giant syringe that is 100cc and graduated to 1cc...works like a charm and is very accurate.
