Iv decided i want to stick with the lb9 in my 88 iroc and also wanna keep the tpi setup (just cheaper and easier at the moment). Im not looking for a track car or nething crazy just want some more fun from light to light . i would like to upgrade the heads and cam to complement the torquy tpi intake anybody have any suggestions? if its possible some budget heads would be nice. Iv read that vortec heads are good but i dont wanna spend money on that vortec intake if i dont have to. i also read that its possible to make these upgrades without messing with the computer is that tru?
