And the way the head gasket usually IS LARGER THAN THE BORE IN DIAMETER, ETC.ETC.ETC.
I know that sounds like it's right, but for some reason if I run zero deck, the motor is a few horse better then when running the piston down in the block to get the same compression. Maybe it's just me.

That's what I meant by "Really?!?" I have the same experience.

Go with what you know. As long as it comes up legal. I used to do those Wissota 2 barrel 9.5 to 1 compression things in B mod, and the zero deck motors were about 9 to 11 better then the 0.030 down motors. Just what I found out. Take it for what it's worth.

Surprising. Same .062" squish, I'm surprised it helps to do it that way. Old as I am, I ain't seen everything yet. LOL

Don't know why, and ain't smart enough to tell you why. It just is what it is. Seen it about 3 times.

Good to know, Randy. Guess Cometic would make gaskets to do that. Been running mine with .030" gaskets, and .033" in the hole.

Yes, we've ran some 60 plus gaskets many times.
