I have found lots of information about this subject on other forums but they don’t exist anymore so I thought I would try here. I know that the eagle heads have a smaller combustion chamber than the non eagle heads so I have to use .75 cometic gasket to bring the combustion ratio down to 11-1. I also know they have huge ports and flow just fine so no real needs for any porting.

my question has anyone done this or have any information on anyone who has. I still have questions about cams like what lift can u go before worries of valve to piston contact or is the push rods length different from non eagle heads to eagle. I have bought a huge amount of parts like Holley Sniper intake and stuff that works for the eagle heads so that’s the reason for the change.
