Im in the process of putting new piston and rings in and ive ran into many problems with head bolts snapping off. 10 of the 14 teen to be exact. which aint a really big deal as long as i can retap or heli coil them. I need to know if anybody knows what tap threads i need for head bolts and muffler bolts. Thanks for any and all help. Pete j
