they will be stock 1998 gt heads. they will not be ported because i dont believe in porting.... i am going to put really stiff valve springs though.... i am also going to clean the heads with soap and water before installing them.... i might try to open up the ports a little bit with some sand paper....

At least use PI heads.

So you want to go from 4v to 2v ? why...and then you want to go to a 98 style non pi head?

antiperformance

how is it anitperformance... there will be less hp loss, due to having only half the valves... that eliminates parasitic loss by 50%, so i believe that i will probably gain a good 70 rwhp, because the crank doesn't have to turn the extra valves. also, i decided to go with non pi, because i heard that the pi heads crack, with over 6lbs of boost....
