    So I bought a pair of HP manifolds (1973) for a hot rod project. Question is would I be safe to grind the ribs off on the drivers manifold? Wanted to smooth them up a bit.

    I'm sure you can grind the rib off but, Chrysler would not have added extra material for no reason. It's a gamble but, your bet to place. Good luck.

    I think the only reason it is there is for the heat riser shield.
