My data does not have a ARH code listed anywhere, only AKH comes close. I have a paper listing at home which might have more codes, I'll look when I get home to night, unless somebody else can crack this by the end of the day.
14093638 casting can be built as a 2 or 4 bolt, 350 block. It is roller provisioned but as built can have a flat tappet cam. If it went into a car it got a roller cam, if into a truck a flat tappet.
