Can someone give ne the formula to figgering compression ratio when
the head cc is known, the gasket thickness is known , and the top of
the piston to deck height is known. That would be a flatop piston with
no reliefs.

A while back I was askimg what I could do to raise the compression
from about 8.2 without changing pistons.  One person recommended a 60
thou. mill of the head, but I don't want to mill my new intake
manifold to match.

Someone mentioed changing to closed chamber heads which I did not want
to search for and pay what they are worth.  The fog in my brain parted
and a pair of 383 heads became visible in my parts stash.!  Those are
516 heads and ports look very close to my late 440 heads.  The intake
valve is the same size, but the exhaust  is smaller. If I put the
larger hardened exhaust valve seats and valves in,  wouldn't this be a
good thing?..........................MO
