Fellas, was looking for some thought and suggestions on head choice. I just pulled the motor and have it down to the block. I ran numbers on compression with my current set up and have 10.24:1. That is with 60cc combustion chambers that my current 388 heads have (1.72/1.5). I have a couple of options: 1) re-build my current heads and it is what it is, or 2) purchase a set of aftermarket heads (looking at trick flow's 62cc combustion chamber to keep compression right around 10:1. Can I get good flow/power out of the 388 heads after being rebuilt and polished and ported, or are the valves going to limit what I can do? Budget is a factor because there are a lot of other things I would like to do and it all adds up! Going with roller rockers and a hydraulic flat cam, haven't picked out the cam yet but def going with some lift thats why I want to keep my CR up.
