Well it looks like im taking the ITR head off and im gonna be putting the 92 GSR head on my c5...i think the 9k rpms finally got to my valves...so why not go ahead and build the GSR head I need some high compression valves- supertech ( prefer Skunk2 if can get them cheap), CTR pistons, Mugen gasket, GOOD head studs (i dont like my arps), and valve seals...and if someone could tell me the best place to get my head ported and worked for around 700+- a hundred I would be greatful... thanks

 

i have brand new ctr pistons w/rings and pins 300 shipped
