the l92 heads are similar to the ls7 they just are not cnc ported and they have a smaller bore and smaller valves and do not have the trick 12 degree valve angle the have the ls1/2 15 deg valve angle so the ptv clearance is not as good as an ls7 head.

I just picked up my 08 Vette, A6, Z51, and that sucker is fast. I think it would hang with my Camaro from a roll and my Camaro eats stock Z06s for lunch.

Stock C5 Z06s or C6 Z06s? If your Camaro can eat C6 Z06s, then it will eat the less powerful regular C6 without a problem.

I wish my new Vette would keep up with my Camaro from a dig but that is very far from reality, but from a 50 mph roll the Vette feels strong enough to keep up with it. I suppose the six speed automatic in the Vette helps by being able to drop down to a lower gear. Bear in mind that this is the opinion of my buttmeter which isn't the most accurate speed measuring device known to man.
