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.

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.
