Thanks for the support JMB! I wasn't trying to impress people with what these things can make, hell I have dyno numbers of that engine making anothe 30+hp with different cams & stuff. I was just trying to show power potential from a simple head swap.

You get water temp numbers, oil pressure numbers, etc. for each pull and the ONLY part that was changed was the cylinder heads and disuse of the vacuum pump. The purpose of the test was to show the difference the heads could make on that setup. What are you expecting, an ET difference from both heads? Come on man....

Excellent numbers! Was that the vp 113 or another brand of 113?....the oxygenated VP is making some good power from what I've heard. Next time you're on the pump, it would be interesting to see if you could make it run on 93 octane. The bsfc was interesting...It's not often I see a "relatively" low compression engine run best that lean. Good work on the heads! We're going to start seeing a lot of 700+ crank pump gas 454 and larger cube engines in the near future. -Brian Nutter

We've shipped about a dozen sets of them so far with typical gains of 35rwhp-45rwhp based on decking. We gained something close to 100rwhp with heads & cam change in our c6 z06!!

How do these heads perform in the lower RPMs. Your dyno pulls start so high in the RPM range, I would love to see what they would do in the lower range for a daily driver.

Oh and what did the GTO make?
