I hate to poke my head in here with all of the ROD guys, but keep your eyes open for the newly designed Trickflow Heads for the 2v cars. 300hp NA with stock PI cams and intake isn't out of the questions for a stock C/I/E 2v....
The 2v's have some problems, they have crappy rods as said before and shoot plugs out of the heads...I am young and only have had a 2v GT but the potential for both the ROD and MOD motors are both there, each just has to go another route.
