Salt water in the valve guides.
Rebuilders won't touch heads from sal****er boats.

That sort of cuts down your options, don't it?
But why is that? I can see how the SW cooled heads might have
more of the passages eaten away, but they could grind, revalve,
respring, and reguide with no problem. Just make it clear future
cracks aren't warranteed, same as any head rebuild.
Anyway, I'm only batting .500 with shop work on heads.
I don't know anything about those boat engine manifolds, but I guess
that's how the salt got in the guides.
The other thing that doesn't make sense to me is how the piston hit
the valve, because I thought that engine was non-interference.
Couldn't find that's a fact anywhere though, so maybe I'm missing
something.
Seems like there's big differences between car and boat engines.
Think I'll get an O/B.
