helpful hints
when putting 350 heads on a 403 block you MUST drill one of the dowel pin holes on the head. apparently olds used different size dowels to keep line techs from putting the wrong heads on the 403 blocks. If you dont drill them out YOU WILL break the dowel pin bosses off of the block. (dont ask me how I know this to be true).
