It sounds like I need to re-establish location with a mill cutter and maybe open up to 3/8" dowel and not just re-ream the block holes.
Stock Pontiac dowels are about 0.3096" diameter. With the Milodon splayed caps that I have, a 0.3096 dowel will drop into the holes, but a 0.3125 is not even close to fitting.

And BTW, I have bought dowels from http://www.precisionautomotivespecialists.com/. That is the only place I have found proper 0.3096" dowels. I also like the extra length of his.
