are the tops of the head bolts stripped ir is the head bolts spinning in the head? if its just the top threads that are stripped, just unscrew the long bolts and replace them with good quality bolts or allthread from the hardware store. also get new nuts for the top. The head bolts and studs in the motors are as week as plastic i swear...lol
