Help Me Out Before I Purchase
Like plaintoast said you need to know the effective head volume or the part# of the pistons that are in the block. If you don't know you can't buy the heads with the correct combustion chamber. The cam and the heads you are going to purchase are great but you need to know which to buy 64cc heads or 76cc heads. If you have flat top pistons which have a 7cc effective head volume the compression will be too high 10.88 with 64cc heads. With the pistons you have in the picture and if the deck of the block has not been milled your compression is about 8.99 now.
