Thanks Al for the quick reply back. I did grind a substantial amount off the valve cover and keep grinding until the MSD distributor would fit in place and rotate a tiny bit for timing. Now however, there's not much of the valve cover left to seal to the head surface. Maybe an 1/8" left to seal to the head. I'm pretty sure it won't seal up with such a thin amount on the valve cover left to seal w/o oil leaks.

I'm trying to figure out here how to attach a couple of pictures for you?
