Pulled the head off last night. Came off easier than I expected. Cylinders looks ok, no rusting or scoring and the top of the pistons look fine. But the inside of one head had some dings like a piece of ring was flying around in there. I'm hoping it is old damage taken care of at the last rebuild. Compression check done when I bought it was good. Will put a new gasket in this weekend and do a compession test. Wish me luck because I don't have $$ for new engine this year.

PS. Not looking for trouble (already found it when I bought a boat) but if I need to replace rings do I need to tear the entire engine down?
