I have 350 that right now has 9.5 compression with 882 heads. I'm new to working on cars so I was wondering, what would my compression ratio go to if I put on set of 64cc Trick Flow or Edelebrock heads? I know that I can get 76cc aftermarket heads but was wondering what these specific heads would do to the compression. The car needs to run on pump gas so I'm trying to keep the compression down. Thanks for helping out a newcomer.

Your compression would be raised to around 10.7 depending on what thickness head gasket you will be using. You will have a little less compression with a thicker head gasket. With aluminum heads though, you can go up 1 full point in compression verses cast iron heads. So, you will be fine on pump gas with say; 10.5 compression and aluminum type heads...
