Reply to "351 Block Question"

Jeff

Its kosher.

The heads are located by dowels that are concentric with the two outer/lower head bolts on each bank, the holes you are puzzled about are not locating pin holes. BUT .... yes there is a little shallow hole on each side of the block in that location (between the two middle cylinders). Its normally got a little pin in it that's flush with the deck, so some guys think it is a round indentation in the deck and never realize there's actually a shallow hole there. I have no idea what the purpose is.
