my st170 has been having some issues lately with water vanishing, lack of power, white smoke so decided to whip the head off and do the head gasket

with it just sitting a couple days cylinder 2 was an inch deep of water which is what i suspected anyway, on looking at the head it seems the water jackets have corroded fairly badly im guessing due to previous owner running brown sludge as coolant.



















my first thoughts is this is beyond repair, but a second persons opinion would be great. i don't think a scim off the top is going to fix this head
