I have a 6.0 lq9, and I am going to put some 205 AFR heads that have been milled to 63 cc with gm head gaskets. Am I going to be able to run 93 octane pump gas without a problem?

what's that about 12.7:1 compression? 103 octane here you come.

I do not know thats what I am trying to figure out. They were milled to go in a 5.7l LS1 by AFR.
I got in touch with AFR and it is going to be aroung 11.0-11.1:1 not 12.7
Yeah, it was just a WAG. RSR Static Compression Ratio Calculator
11.37:1 with a .045 gasket, 4" bore, 3.622 stroke, 0.0 deck height, flat top piston and 63cc head chamber.
