Yup, this is my old setup which was quite impressive. The heads were hand ported and flowed by Joe Prince, one his last sets that he did before having troubles. I never cc'd the runners, but I know the heads were milled 0.030" to bump compression a little. The valves were all lapped in by hand and there was an easy 40 hours into these heads as every single runner, exhaust and intake was flowed and matched.
When I dyno'd, I had an ls6 intake on the car, stock throttle body and maf, macs with a crushed ypipe, see image below, and a box tune that was far less than ideal. On an optimized setup with a better intake track (maybe a fast or ported throttle body/maf) and a better exhaust, this would certainly put up numbers that would have people scratching their heads with why they went with monster cams.
I dyno'd this summer on a dyno dynamics load bearing dyno, which I'm not 100% confident in, but it put down 468/460, which on a dynojet I'd guess would be around 440/425. Not bad considering the amount of low end torque I had. The only reason I sold this setup is I'm planning to go with more cubes in the future, and I bought a set of PI heads that will grow with my cubes in the future.
Here's the dyno from the week before I took off these heads...
Whatever the actual numbers are, look at the torque curve.... It's not a peaky setup that you need 4.56 gears or a 4000 stall converter to enjoy.
Hell, if it helps, I'll send my tune file to who ever buys this combo. It might not be perfect because I had a Fast 90/90 combo but it'll get you damn close.
