02 Z06 Stock Head Flow Numbers?
Can somebody post the flow numbers of the stock heads on a 02 Z06 at low and high lift?
I want to match it with a cam that would produce the most power on stock heads.
I hear good things from the Cartek 3X cam. Anydoy knows the duration at .050 for this cam, LSA?
Thanks in advance for any info.

I think I found the flow numbers for the stock heads. ~260/183 I/E at .550
Does everybody agree?
Also, about the 3X cam, I know it may be not be the right thing to disclose the cam spec here; if somebody can PM me the specs, it will be great. I know a bit about cams, by knowing the duration and LSA I can tell if this is a cam I want.

The flow numbers were actually 260 @.500 and 183cfm @ .650
You can see the numbers on this chart which is half-way down the write-up here...
The heads were flowed on the MTI Super Flow bench.

Unfortunately, no. But those heads are NICE!
I did up a spread sheet a few months back to see where the different heads came in at, and at what cost to give me and a few buddies what was the best $$$ to performance deal. The "disadvantage" in price for the CNC LS6 heads (by LPE) was the additional labor and cost to upgrade the springs to something that could handle at or above a .600 lift cam (LPE claims up to .570 safely). When that cost was added, the AFR 205 heads came out the better deal for near identical numbers. I am sure you can contact LPE for more info even though that head is a GM product. I am 99% sure they (LPE) did all the work.
