Im currently looking at a pair of PI heads. Im assuming the Performance inhancement would be port and polish correct? They come with cams, and valves and all including valve covers and am wondering what would be a fair price to pay. They are windsor heads and came off a 2000 GT.

pi's arebetter flowing (more cfm) casting than the pre 99 years. Don't think they are ported and polished. Don't you already have pi heads on your 02? I have a set for sale if you want to make an offer.

op unless your just buying backup heads/cams there is no reason to buy them. They are the same ones your car came from the factory with. 96-98 gt's do a pi swap which consists of putting 99-04 heads/intake on our block. The flow on the heads and intake is much greater and the compression is bumped up which results in a nice gain in hp for us. PI stands for performance improvment which is just the term given for you generations heads/motor/cams/intake.
