The words "Power" & "Cheap" do not go together. Also, "Cheap" & "Heads" do not go together either. Assuming you have a 99 or newer GT (some detail helps here), having your heads ported, when coupled w/other mods, will return significant power increases but not cheap. Overall, the least expensive, least hassle, big power gain is bolting on supercharger.

k first of all i have a 96. i know pi heads and intake is the way to go but dose anyone know where to get them cheap. are they ok to use off another car. are there anythings i should be carfully about like intakes cracking? thanks

-- the swap is worth doing; even just the PI intake & cams is big gain. Let me know when going to be in Arlington or maybe meet someplace and see mine.

The price on the Livernois intake manifold kit went down $150 recently:

worthwhile gains from just the intake swap there.
