hey guys
Not getting proper oil pressure and no oil to the rocker arms. I just rebuilt this 1958 235 and i know the oil line was deleted in the lifter galley that year and instead ported straight through the head and through a special bolt. Out of all my head bolts that were in there originally, there was only one irregular one, with a grinded side to it. None with a hole. do you think this is my issue? do i need a head bolt with a hole? or do you think its something else?
