The only way to truly tell if it is the heads or not is to pull them and run some tests. If it does turn out to be the heads, I'm sure terry will be more than happy to work something out. I just don't see how one CNC head can be that much diffrent from another. Bashing a sponser without proof is . If you can PROVE that the heads are the problem, I'd be interested to see. Pulling one of the heads and flowing it with the intake on and off would be a good place to start.

Chris, I'm not saying your 6 cars aren't a good excuse, but why would 1 car with similar mods do so well why yours don't. If your saying all the cars lost power, why not post numbers from before and what set-up they were running. You also never answered why the 6 cars you did are so similar in mods and so far apart in dyno numbers. I'm not trying to stir the pot, just stating the obvious.

For the record yes I did dyno the Patriots on 3 cars with changing just the heads with absolutely no other changes other than tuning the car to 13.0:1 flat with 28 degrees timing and no knock on every car. Against MTI Stage I 5.3L heads they lost 5rwhp, against absolute speed Stage II 5.7L they lost 12rwhp, and against stock LS6 heads they gained 10rwhp. So while I didn't post these intermediate graphs I do have them at the shop because unless you change the heads, dyno, change the cam, then dyno again you can't pinpoint gains or where the lack of gains are

Terry,

I'll call you tomorrow to discuss the situation

Chris
