PRC 5.3L heads For Sale!
 

I selling my PRC stage 2.5 5.3L heads and custom 230/236 cam. The heads are milled to 61cc's. The valves have been de-shrouded which improved mid lift flow. They have PRC dual valve springs and 2.02/1.575 valves installed. Right now the heads are still on the car but will be removed very soon. The cam is a custom Comp Cams 230/236 .613/.601 112+3LSA 109ICL. This Setup made 447rwhp and 415rwtq and went 11.0 @ 124 n/a in my full weight 6spd car. This setup responds well to nitrous (10.08@136 w/.067 jet).

CAM IS SOLD

$1000+shipping for the Heads
Local Pickup preferred.

Cam is Sold, Heads are still up for grabs. Will post flow sheet soon! Asking $1000 for the heads. Keep in mind, I had these head reworks by D&F in Berlin NJ. These heads will out perform what PRC sells.

Those heads are tempting to throw on my tbss, how many miles are on the springs?

About 15k miles. When I did my forged bottom end, I sent the heads over to D&F and them rework the heads. They did a valve de-shroud, milled them to 61 cc's, touched up the runners, installed new valves, locks, retainers, and springs. Once I find my paper work from D&F I can post it and it has the info on flow #'s and spring pressures.

ohh realy...what heads/cam are you going w/ now?
