Anybody know the combustion chamber size on 1956 Lincoln ECU heads?

They are big..  I have CCd them anywhere from 80 to 88 cc

Thanks.  Just trying to compute compression ratio.

What compression are you shooting for?   With flat top pistons you will be lucky to get 9:1. I have cut the heads as much as .060 and gotten them down to about 75cc. That would be ok for a street engine but it gets dicey getting head gaskets to hold if you get up above 10.5 compression
