Just started tearing down my brand new 212 predator to install some go fast parts. Upon inspection of the cyl head I found what looks like about six or seven cracks in the dome. They r visible with the naked eye and u can feel them by running a finger nail across them. A little closer look with a magnified eye piece and now I can't tell if they r cracks or witness lines / flaws from the casting process. They all start at the very edge of the dome and extend to the valves or spark plug hole. Funny thing is they don't continue out to the flat surface area or down the plug hole or valve (pockets ?) just appear to be on the roof of the dome surface. Anybody seen this?
I tried to take some pics but my camera can't pick up what I'm describing.
Gonna put a polishing head on the dremmel tonight and see if they will buff out I guess.?.?.?
