I heard if the head gaskets go and i 91 it is a huge bill becuz of man labor

Come on now, how many times have I covered this. Yes it's a huge bill if you can't do any of the work, but if you can do the work it's only a $300 deal at the most. Removing the head requires almost everything else to be removed from the engine also, meaning it's very labor intensive.

whats the difference between a stopper and bead???
