Are these heads good to run-(water passage corrosion)
Guys, Cleaning my parts before I start assembling my 5.3 and I noticed the water passage on both heads are corroded in the same spot. Doesn't look too bad but I wanted to be sure they are still good to run without worrying about a leaking head gasket. These are 806 castings. Truthfully, I may have did it while trying to clean them with easy off and leaving it on too long. It is the only visible corrosion on either head. Thanks in advance!

tape a large sheet of sandpaper to a glass table and move the head across it at a 45* angle one way then 45* the other way (low left to high right then low right to high left) a few times and see if the surface looks evenly cleaned up
if it does not make a few more passes but if it becomes obvious it isn't going to clean up evenly, take them to be surfaced by a machine shop
