Ok. I did some reading and the primary metering rods I have are triple taper with a .053" diameter (53C). In addition, the primary jets are .070" in diamater (70). Finally, my secondary metering rods are stamped with CH, and the hanger is stamped with H.

Can I replace my primary metering rods with these rods available from Summit?

These rods are .052" in diameter and I assume they only have a double taper (I read that Oldsmobile was the only one to use triple taper rods). I just want to make sure these aftermarket rods work correctly with the jets in my carburetor. Right now I don't plan on changing the secondary metering rods or the primary jets unless someone knows of a good combination to use on a street driven engine which is mildly built.

I appreciate all of the help.
