Hey guys,
I'm getting ready to slap on a set of L92 heads on my 05 C6. Haven't gotten my cam yet but it will be something around a 224/228 with no more than .600 lift. The car is a daily driver so reliability is a must.
My question is:
How much compression can I run on pump gas (91 octane)? The higher the better so i can retain as much bottom end power.
I know the pistons will need to be fly cut & heads will need to be milled.
Thanks guys

We are getting away w/ 12.5:1 on the ls7s using 93 oct. and 23x or 24x cams. I run 11.9:1 myself on stroked street LS7, 22* timing and 93 octane. No issues....

With a 224 / 228 cam you may not need to flycut the pistons. You may also just be able to use cometic thinner head gaskets and get the compression bump you need. 11.5 - 11.75 to 1 should still be fine on pump gas.

So what do these heads like better?
smaller cams like a 224/228 or something bigger like a 232/236?
I want something that can keep a good amount of bottom end torque but screams up top. This will also be going into a daily driver so i don't want any surging or shaking.
LG motorsports is recommending me to go with their G6X3 Executive cam.
Thanks for all your opinions guys.

Good luck
EDIT: I have not evaluated PTV for the suggested cam. got to be carefull if you do not end up fly cutting.
