Hi I am new here and to Polaris somewhat. I am replacing the intake valves on my 2005 Polaris Predator 500 and I ordered the kibblewhite Black Diamond Valves. My question in do I have to do something to the seats to get them to sit right because I know you cant grind the black diamond valves. will it just sit itself in place (Break In)? Could someone please help point me in the right direction. Not to the local machine shop either lol.
