"some1 said not to add a thicker head gasket to decrease static compression as it increases squish. this is NOT TRUE, a thicker head gasket will decrease both static AND mechanical compression ratio."
A thicker head gasket will decrease both static and dynamic compression ratio, but it will also increase the tendency of the motor to detonate on the same fuel because it increases the width of the squish.

You were a "johnny-come-lately". I started in the summer of '58.
"i use a cam with a relatively HGH numerical duration which ALSO allows the use of more compression in any situation as hgh duration cams have hgh amounts of overlap and thus bleed off cyl pressure and lower static compression."
First of all, you don't lower static compression ratio with cam timing. You lower dynamic compression ratio with cam timing. And it isn't the overlap that makes the difference. It's the intake closing point. There is insufficient cylinder pressure at overlap to make any appreciable difference.PLANET EARTH, INSANE ASYLUM FOR THE UNIVERSE.

I had "Static" once but I found that the radio was bad.
I'm with Don this could be pretty good. Go gettum Tech!!!
RolandProtected people will never know or understand the intensity life can be lived at. To do that you must complettly and totally understand the meaning of the word "DUCK"
