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.

.. yeah I think they are pretty much L92 heads with hollow stem valves!? and an L92 block with L76 intake... But cant seem to find any concrete information to confirm.

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.

Bear in mind that this is the opinion of my buttmeter which isn't the most accurate speed measuring device known to man.
