In my experience, those .500 dowels are for a Chev, they would not fit in my block. The good old mopar performance ones that i used fit perfect and they measure at .497. Those dowels from mopar performance are in my treasured special parts drawer.

That's good advice, I was wondering if the Summit .5" were exactly .5" Doesn't sound like they would fit if the hole is .5". .497" makes sense.
