also depending on what head you pick you might be dropping a full point of compression 516's have about 76cc champer or less.



Yeah, that's an issue as I was told the block is a 73 440 with stock piston and rods and that jives with the block numbers, but I haven't pulled the 516's yet. The heads I bought are listed on 440 Source web site as 80cc. I'm looking for the thinnest head gaskets I can run on a mostly street motor. I'm thinking the Cometic MLS .027 but they are expensive. I don't plan on reusing them much, but one never knows...
