Default Any Idea about the CR here?

I am planning a LQ9/L92 head engine and I didnt happen to think about the compression ratio that I would achieve with this combo. Im not totally sure about the head gasket that I will use, but I will probably order the head gasket kit that SLP offers with their L92/L76 package.

The bottom end will be a stock LQ9 taken from an Caddy, so that means flat top pistons. And the L92 heads will more than likely be untouched, meaning I wont purchase the milled/P&Pd L92 heads from SLP. As long as I am in the 10 to 11.5 range I am okay with that. I just wanted to make sure this wasnt going to be a 8.5 or 12:1 setup. Thanks...

If my brain is working right then i think you will be in the low 10s depending on gasket size.
