I have a set of heads that have been milled .010, with a stock deck height, and a stock bottom end. What will my compression ratio be if I use a .026 thick head gasket such as Mr Gasket 5716s? Thanks

 

I guess and I say guess b/c I dunno the exact cc of the combustion chambers but its between 11.1 and 11.4.

 

Well, stock the chambers are 55cc (I think) and my chambers have been polished so that might add a coulple of cc's, but I would think that being milled .010 they would still be very close to 55cc. Basicly I'm wanting to get 11 to 1 out of it. So you think the .026s will get me there?

 

Your chamber is now about 1-2cc smaller, and you have about a -6cc valve relief, pistons .030 in the hole.... around 11.0-11.1:1

Damn I didn't know the pistons were .030" in the hole! I was putting in .020" and using a smaller combustion chamber and coming up with around 11.5:1, which I knew couldn't be right.....
