Nice! 11:1 on pump gas?? I've been curious what you can run for compression on 91 pump gas?
Iron heads vs aluminum? I believe you can run more with aluminum?

I used a thicker head gasket to pull it down a bit , and just don't go crazy on timing. All good .

Are you saying you're at 11:1 and the quench is above .045" and you plan to get by with pump gas?

Cool! Should be a lot of fun!!

Pistons and deck clearance weigh in on compression totals of course. The Pistons were 11:1 , went with I believe a .045 gasket. But to be honest 11:1 is not to far out of the scope for 93 octane. I believe GM used a .020 thickness

There are some really good reads on the issue actually. I'm sure there's plenty right here on the forum .

There's just alot of factors IMHO when calculating compression ratios. Heads 64 cc or 70cc , cam etc.
