Yeah if you make sure all the dirt and stuff is cleaned around the holes and you are using a 3/8 12 point socket you shouldnt have to worry about them stripping. i could see if you had dirt in the hole and it stripped the top of the head. but i have had mine off numerous times and havent had a problem.
I just bought some new bolts for my other set of hipers. They have them for $5 for a 12 pack..
