Any recommendations on reputable options for cylinder head repair shops? I’m pulling the head off my yz250f that has a blown head gasket. I’m hesitant to ship it off to someone without a recommendation. I won’t have specifics of what it needs until I pull it off, obviously. But just trying to get ahead of the ball. (Bubbles in radiator when I start it, white smoke from the exhaust, hard to start, hard to keep running, and oil looks funny. I put fresh oil in, drained it, and it came out kind of dark with a whiteish tint as well. If that makes any sense?.) Thanks.
