Pulled end cap off a manifold today of a 440 that has set in the boat for 10 years on blocks. Used a camera to look inside and they are pretty rusty. The question is how much is too much and what have others done for this issue?

Were they full of water? Fresh/salt?

Dry when I opened it today it's been sitting for 10 years. I'm trying to figure out how to post pictures yet but I took some of the inside of the manifold. Boat is always in fresh water.
