The total combination is worth far more than simply throwing a pair of heads and a cam on a car. You've seen many shops and several DIY'ers with TFS 215 heads make 500 RWHP, you've also seen DIY'ers make 430 RWHP with the same heads. This is why it is important to work with a proven package within your budget.

We've also had LS6 heads make big RWHP, but the results are much more inconsistent due to casting shift of the OEM castings. The larger port volumes on the ported OEM casting also make them more sensitive to cam timing events and practically everything else.

Definately send them over or bring them down if you'd like to get them tested at the same time we're doing our testing. We don't have anything to hide here, if you want to see a same dyno same day test then we can throw other heads on at the same time!

I have the PRC LS6 stage 1 to go along with a G5x4 cam. Cant wait to see what the car puts out. I've heard great things for PRC's and for the price you cant beat it! Hell for the extra money you save, throw some NOS on it!! lol

Cartek is sick for stock castings but for that kind of money I would go TFS.
I am VERY happy with the PRC's in sig and my old Gen I buddys cannot believe the bottom I have with such a thumpin cam. I have at least stock torque 1800 (lockup) and above and put down +350ft.lb rear wheel torque from 3500-6300. My torque graph is nearly flat peaking at 383 For the $$ I spent I am very happy with TSP.
