    I recently bought Comp Cam 1622-16
    Pro Magnum rockers. I have 8 rocker arms with a #1 & 8 with the #2 cast in to them as in the photo. Is one number for intake & the other number for exhaust? If so which is which? They came on the shafts in no particular order or reason. Can anyone help me out? Thanks!

    There are no lefts or rights. Guessing that the number is just the mold number on the casting.

      I think so also. But both shafts have 4 of each type. What are the mathematical odds of that happening? Going to send a Email to Comp Cams & ask. Im hoping someone else has noticed this before?

      I bought used the same rockers. No lefts or rights.

      Spend the time lining getting the tips perfectly lined to the valve tips with shims and/or shaving sides of the hold down clamps.

        Mancini has shims. And they are 4 miles from my house. I plan on getting a couple sets. They are not expensive.

        The confusion will really begin if you look at the stock stamped rockers. There are left and rights of those!

        As for the shims, yes they area good idea. If you don't reduce the sloppiness between the rockers, besides being somewhat mis-aligned, they'll be noisy too.

        I'm happy with my purchase. They are quality parts. Not worried about alignment. More confused why I have 8 of two different casting numbers. I have written Comp Cams this evening already.

        You need to worry about alignment and geometry. They will both need work.

        Yes I agree with your statement. You read my last post wrong.

        That's what happens when you get old. You can't read you young whipper snappers.

        If you're not a young whipper snapper, then I don't have a good excuse.

        Sorry.

        Should have said not worried about fixing alignment because I'll be using the shims from Mancini.
