Stock 1984-85 pistons are forged and produce 9:1 compression with the cast iron heads. If you forgo the block decking and only surface cut the heads to be sure they're straight, you'll be close. Other then that, you are going to have to assemble a pile of catalogs, along with YOUR engines specs, and figure it for yourself.

RACE ON!!!
