drill and tap for a relatively large bolt (3/8, 7/16), cutoff wheel and smooth off excess bolt , and then drill and tap stock size. Did it once on a rearend yoke on a truck, and got away with it. No problem on a low tension valve cover bolt. I've done this on a rocker shafts hold down bolt with no problems and I did it by hand.
