Unfortunately I tossed the old bolts in the trash last week thinking what the heck am I keeping used head bolts for anyway (damn). When you say cut a groove into the treads do you mean cut a groove the length of the bolt so it go's across the threads.

I'd shy away from using a tap because if you get it off centered you'll end up cutting into your good threads, which is very easy to do with an aluminum head.

Are these brushes that could fit into the head bolt holes, if so where did you get them from because I have never seen them that small.
