If you send your head to RB, do you need to rebuild the top end or anything or is it ok to just remove the head and put it back on when it comes back?

there is nothing Ron does that makes you have to rebuild. If you are due, then it would be dumb not to. Also if this is a 220 with a stock piston, you would have to be an idiot not to swap to a Wiseco.
