Okay. is GMPP GM performance parts? If they only make 1 intake specifically for it, won't they all be the same? Regardless if buying from GMPP or ebay? That little mod list sounds good for 60 HP. I'd like to do those, a throttle body spacer (just for the hell of it, and the little whistle lol) some headers that would go good with it, and would I need to upgrade the cam at this point or would stock be okay? I've heard these TBI cams are a joke. Also, with the upgraded rocker arms would I need to change the valving or anything else. The heads intake and rockers will all work without weakening any other aspects of the internals
you can change the rocker arms without changing anything else, the reason i say to install 1.6:1 Rockers, is to increase lift, stock is 1.5:1, so its sorta like getting a new cam.
You can buy the intake anywhere you want, but GMPP is the only manufacturer.

Your other choice is to get a carb intake and put a TBI adapter plate on it, cheaper route, but WILL require tuning to get rid of EGR.
