799 milling
How much should I mill 799 heads to reach 10.9 compression if using the gm mls gaskets?
I found a chart showing the chamber cc's compared to compression, but wasn't sure how to translate to milling...

I just got my 799's back from Texas Speed, and didn't mill any! Instead, I'm using the Cometic .040 gasket set as opposed to the MLS gaskets. My static CR will be 10.95 when done, and I will have added quench, which helps against detention and I won't have any PTV issues.

ection....quench is the distance from the piston @ TDC to the cylinder head.
A .040" gasket is thinner which reduces that distance (CC's of volume)..
milled, you'll need about 61cc chambers. So starting from 64.45 cc, a .021"
cut should put you where you want to be..this will also affect push rod length
