Ok 1. your not gonna gain 80 HP from a cam swap not being rude, just realistic. What are the casting numbers on the head, Have the heads been ported? A stock valvetrain will hold 500 HP ALL DAY. i would put new lifters in with a new cam.

LQ4 motor 317 cast heads. does that do anything? and i didnt mean just cam. im doin cam heads full bolt ons and maybe harland sharp rockers and different pushrods.

317 are good heads,you need to mill them .I would keep the stock rockers and install some compcam trunnion bearings.get a push rod checker ,$20 and measure for the correct length push rod.maybe consider a torquer v2/3 tsp cam pkg ,or a EPS cam.get a ls6 intake ,you can retain your stock TB.
