Heli coil the toes and use the same holes. The hole patterns for the heels are so different you won't have any problems putting new holes in for fks from px. I would heli coil the heels to if you're having problems with tear outs
Are you sure? These have been drilled for the original mount, and moved forward 2cm after a tear out? I don't even know if the holes have been plugged. This might be a completely noob question but what is hellying?
