he told me that with these heads and all other boltons,cam, ls6 intake, and tune, i have the potential of just under 400 rwhp. thats pretty impressive. i think im gonna head in that route. i would like to see some numbers though.

Recently Closet Red Neck's Z71 ran a 13.08 in 80º weather. Given the weight of his truck he's seeing close to 400rwhp if not a touch over. The cam in his engine is in the mid 220's. I'm sure he'll get to the dyno in the near future and post the results.

Concerning his customer service...When he and I were planning out my 370 build a guy came into his shop with a set of heads that had lifted on him at the track. Heads were not from WCCH and richard took a look at the guy's heads and spent 45 minutes explaining to the guy where it had lifted, what the marks on the heads had meant and what he needed to do to prevent this from happening again. No charge, no fuss, no worries, just one HP junkie to another. As far as customer service he's the best and I'll stand by his product...see sig.

I have set of these heads on my truck and it loves them!!!! After gears and a tire change...........new times. I will get it dyno'd soon. I just don't know when I'll get a chance to get down to Allens. I should've ran a 12 that night I ran the 13, I couldn't get the power to the ground after the track went to ****. If I can get a Z71 into the high or mid 12's, that's pretty good proof.
