Sorry, not a great plan. If the stock cams are OK, then leave them well alone. New OE cams/rockers are not necessarily any better than the ones you have in there, and in some cases could need lashed.I am thinking of replacing my intake cam/rockers preventive, before letting install the REV300 kit. Any idea of the cost?
If you're worried about their condition, inspect them by pulling the cover. If wiped, then replace. If, OK, leave alone. Period.
If you're worried about them wiping, you can run some oil break-in additive (essentially, zddp) with each oil change going forward to bring the Z/P content up to about 2Kppm and that should certainly help ease your mind.
Enjoy the install:up:
