ProComp/Speedmaster aluminum heads

Are you going to do any special cleanup on the decks? I'm in about the same spot. Prepping to put the aluminum heads in place of the J-heads. My decks are smooth, don't seem to have any buildup, but there is staining. I figured I as long as it is smooth, I can run with it? I don't want to get abrasive anywhere near the cylinders if I don't have to.
I don't think there's any getting the stains off of the block short of having it resurfaced again... I'm just going over it a million times with white paper towels carb cleaner and a couple brand new razor blades. Maybe the gurus will try him in but I'm just getting it as clean as this human can possibly do it...
