Snapped Exhaust studs part II

[anutz]

So after a few PM's and maxzer1500's comments about scotchbrite on the bores, i am looking into it.....any recommendaitons on what type of grade to use?

Also i am thinking can i use the scotchbrite for preparation of the Head and Cylinder gasket sufraces, i use Wet and Dry on my last one after i used a sharp razor to remove old gasket material..

If i can clean up all the important mating surfaces carefully and then scotchbrite as well as on the bores it would be good...
