for the money the PP heads are just okay. You can send your stock heads to WCCH and have them ported and they'll be equal to or better than the PP heads. There is a reason they're so inexpensive. I've talked to builders that claim they've actually lost HP on the dyno after installing a set of PP heads from a stock engine.

got your email....sorry for delayed response having some family problems...yes you have a very similar build to mine...i was never going to put better flowing heads on mine it was built in mind of having a magnacharger on top...with that combo I would think easy 400 at the wheel if not more with a pulley change...
If you still have stock tranny with just a shift kit start saving for a built tranny...it will happen sooner or later and better to be prepaired..

Port and polishing does hurt a stock motor cause I had the same thing done to my car. So any suggestions on aftermarket heads cause i would like to keep the stock heads original incase i ever needed them as back up.
only a bad P&P job will hurt a stock engine.
