I'm looking to upgrade the heads & cam in my 2004 GTO, and I'm wondering who out there in the performance world (LPE, SLP, MDMC) gets the best flow numbers and HP increases over stock on there CNC Ported & Polished LS6 Heads & cam packages.
I want the car to still be streetable...
My ultimate plan for this car is to upgrade to headers, then cat-back exhaust, then the heads & cam, then a blower.
