If it helps any, I have about 8 known broken studs and it has been running fine for about a year. Still pulls really strong! I autocrossed it this weekend too. I know it will break loose sooner or later but for now im gonna wait for the flutter noise. My guess is the heads have somewhat welded theirselves to the block. 30 years will do that. Just an exteme example. rebuild is on the list, just dont have the time right now
