It is using the .904 Mopar lifter size correct? If so don't worry about wiping the break in lube off of it doing the adjustment as long as you prime the oil pump and rotate the motor over while rotating the crankshaft several times by hand while priming it as long as your not running more than 350Lbs opened pressure over the nose of the lobes
You could set the preload with the intake off also and then pour some extra cam lube back onto the cam lobes when your done also
