Cylinder head water passage corrosion, opinions?

[Vetal4]

I don’t even know if it’s really corrosion, there wasn’t rust in it when I cleaned it it’s just rough and crappy around the water passage. I can’t even really tell if the roughness is even recessed, it almost feels like some of it is raised. No other passages look like this. Run it? Plane it? Opinions?

IMO wipe it with some red Scotch Brite and run it.

Generally machine shops take a light cut to provide a clean new surface. Often until heads seat in there is some seepage. Many times I will drop in a bars leak pellet. Either way run it.

I'd run a red scotchbrite roloc disc lightly over that and run it

Personally, I'd Sh!tcan it and look for an LS. I mean you're already in it this far

Edit: Just kidding

Not quite as radical is a new set of aluminum heads. Wished I would have done it on the last 350. By the time I found heads that weren't cracked and had them rebuilt it was very close to the same cost.

Thank everyone for the inpu….ill go ahead and run them, seem to be a pretty nice set of heads, except for that.

Spot on.

Looks to be right on the edge of the fire ring. I'd have them cut before installing.
