Average HP gains with aftermarket heads????
I was just curious about the average gains you get when installing heads. I'm going to get my car dynoed this week and wanted to get some kind of idea of what to expect. I dynoed at 350rwhp before installing the LS6 intake, Ported TB and 2.5 PRCs. I'm figuring about 20-25 hp for the intake and ported TB.
thanks...
thanks...

So if I don't see about 400 rwhp then I guess I didn't get a good set then.

I went from 357 to 394 after installing some prc 2.5's from ffhp (milled .0015) on same dyno in similiar(hot!) weather. I had to bump my fuel pressure a couple lbs to compensate. I'm hoping for 420 with some longtubes and less restrictive exhaust.

Now with that said, I am simply saying the heads are FFHP heads, we just out source the CNC work. The CNC work at PRC is sweet and the guys at TSP rock, so this not a bash, just a clarification.

So, the PRC heads that TSP sells are really "Racetech Speed & Performance" heads then right??

the cnc work is only half the job it takes to produce good flowing heads, if our bowl blending and valve job sucked and the heads did not perform would PRC be ok with me callling them PRC heads?
In the business world small compaines out source work all the time, I just happen to be up front about it(not that others aren't).

Wayne, I really think if you hit 400, not over but just hit 400 you need to be in the hall of fame! What you failed to make more obvious is the cam, the fricken hot cam man. I bet if the ppl up top seen that, the replies would be more conservative, like 390 at best. How many ppl dynoed a hot cam at or over 400? None?
Blending and bowl work, your not thinking because of all the untouched areas on your heads are you????
