Well in a feat of immense stupidity I may have inadvertently damaged my cylinder head beyond repair. After removing the head to access the valves for my ongoing "in-boat" overhaul (un-seizing, valve cleaning, new valve springs, new gaskets, etc) I vinegar bathed, pressure washed, stripped, and painted the head. After which I placed it in a large "Tupperware" container for temporary storage and left it on the boat while I turned my attention to other matters. This afternoon I pulled the head out from under the pile of parts awaiting reinstallation only to discover that the face has seemingly corroded (substantially IMO) in a matter of weeks...ok maybe its been months but nonetheless I can't believe the corrosion especially in the area of the cooling passages:
What the head looked like when I pulled it off the motor...
and now...
(Sorry for the 'reflection in the pics.' In my panicked attempt to close the barn door after the horses left I coated the face with a copious amount of MMO to stave off further corrosion while I determine the best course of action)
In the forum members' opinion, would this head still be a candidate for reinstallation, or now in need of resurfacing, or replacing? If resurfacing is what the Doctor orders does anyone have a favorite SF Bay Area machine shop?
at least the top looks good now ...
