Those need to go!
That doesn't look like cavitation damage, just plain old corrosion. Cavitation damage I have seen looks like termites have been working on it making patches of neat round holes.
Just use Flex Seal - if it can fix a boat ?? Bob
I blew 5 of those back in the '70's when I was farming with my first D2. Next comes a pinhole, complete miss on that cylinder. Pressure out radiator. Never heard of antifreeze or corrosion inhibitors back then.
Buy new ones, they are not expensive.
May not be expensive for you but Finning here wants $460.00 each

I reckon I paid around $US30 each for my aftermarket ones for my D2 4U, but that was about 6 years ago, things like bearings and gaskets I always buy from Cat, but everything else I hunt out aftermarket
