Ok if you can answer this question you will have yourself a customer! Can I use your heads in my 88GT with Typhoon upper and lower, LT's and an Hpipe, stock fuel system from pump to injectors and stock cam and rockers with an SD set up, and have no tuning to do? I want a rebuild with with some power 260-270RWHP but not have to fuss with the set up like most due when they run H/C/I combo's. I have spent the better part of 1-1/2 years bringing this car back from the dead, and to be honest I just want a good strong reliable 5.0 with nice solid idle and fun on street drivability. Anyone else with simular set up please do give up advice.
