Default CR with L92/LS3 on a LQ9

I've searched EVERYWHERE but the one thing people never talk about is what the CR will be. Many CR specs AFTER milling but never on an unmilled set.

What am I looking at on a bone stock LQ9 short block with a set of unmilled L92 heads?

I'm planning on using the LSA .075 MLS gasket which is thicker than most .4 ~ .5's . Any info would be greatly helpful.

Basically, I want to throw of some decent heads before going FI.

Thanks in advance!

Use an LS9 gasket and the compression won't change much.

Really? I thought this would take you closer to 11.0:1 CR...

I guess they have similar CC sizes right arounf 70cc?
