What do you mean by rings? Not the piston rings, but just the general
condition of the cylinder walls? Yeah, the spots on 3/4 are probably
from coolent. It's very possilbe that 3/4 were sharing combustion if
the head gasket was toast.

Sounds like a good plan of attack. I'd have them grind the valve
seats, put in new guides, etc... I mean it's already out and in the
shop... what the heck. (Gosh I love spending other peoples money. :-)
How tired is this engine? miles?

That's always a judgment call, but you'll have to wait to see how it
feels when you get to this point.
