Ok, I used a srew down type spring compressor....what kind are u using? If there is carbon built up, I would hit that with some carb cleaner to try to get some of it off there. PRobably not really a big deal though.

As for the porting, and valve hole...are you talking about the valve guides? as for grinding the exhaust bump out, u should not hit water in just taking the bump out. It is suppose to be in the short turn radius' that you can come close to hitting water.....and in the combustion chambers......dont know for sure though, I have yet to hit water.
