LS6 motor Q's
 

Ok,
LS6 motor, 10.5:1 CR (64.43cc heads).
I assume this is with a .052 gasket right?
Also taking average out of hole piston at .08.
So theoreticaly the quench on a stock LS6 is ~ .046

So, if I were to change the gaskets with a .040 MLS this should give me ~.032 quench

Now that would mean a .012 reduction in cc (at .006/cc) = 2cc
64.43-2cc=62.43
or a CR increase of ~ 10.7>10.8 CR
So if I were to mill an LS6 (243) head another .015 I should be ~11:1 CR

To sum it up: .040 MLS + .015 mill = 11:1 CR on a stock LS6, W/.032 squish

Would I be correct in this assumption?

ttt..

I would say that you are in the ballpark in being correct, but having to run 100 octane to keep it from detonating itself to death as a result, a pain in the ..............

No need for 100 Octane for an 11.0:1--- 12.0:1 i agree

In any case regular gas is 95 octane here and premium is 98 octane at 1.49$ a gallon.
So no problem on this issue. :)
