trying to get rid of a pr4 head and port matched intake manifold, its ported and polished by pineapple racing from the west coast (no cams), also have a pair of aem cam gears and an ecu rechipped by xs engineering. higher rev limit and better fuel curve for all motor applications. all of the above will work with ls motors (b18a1/b1). the head has no valves and valve springs but does come with the rocker arms. asking $500.00 for everything.
