    Your setup is a LOT like mine. Except I have 1.6 rockers, Explorer upper, and 24 lb injectors.

    Rebuilt EV6 Bosch injectors.

    This was intended to be a baseline pull before winter mods (AFR165's and custom cam), but I'm second guessing swapping the heads even though I already own a set of new AFR's.

    It's tempting to keep the current heads and cam and see how close I can get to 300rwhp with stock untouched 'P' heads and stock cam. I don't forsee hitting the magic 300 mark, but how close can I get?
