    I understand the Rh for right hand. I have manifolds where it says RH1 and another that says RH2. What is the difference between the 1 and 2 stamping?

    Do they both have the same casting number?

    With both having the same casting number, the 1 and 2 could be something as simple as numbers to identify which mold they were cast in at the foundry.
