Milling used heads Necessary? Just picked up a used set of LE1 heads with 1500 miles on them, Do I have to get them milled? or can I just clean up the block and heads and bolt them on?
Whatever method they need to be checked before installing again. If they need any milling it most likely will be something like .004. Not enough to worry about fitment between heads/intake.

Just make sure all the gasket material and carbon is cleaned off of the decks before you lay the straight edge on there, red scotch brite pads work well with a 2x4 or 2x6. Otherwise the straight edge might get held up too high in a spot and make you think the head is not flat. If they are already clean then just look for dings and scratches like these guys said and maybe still run the scotch brite pad across the decks.
