A: matching code #'s?

and im still having heat riser issues ,i don't have a operational one at this time ,so is it wise to just change out the manifold with a new exhaust manifold with the heat riser all in one.because my exhaust manifold is in good shape and i recently change my engine into the super six .it was a one barrel now the 2 barrel ,so had to do all the reconmend details to change to the super six - 225.so what do you think on the heat riser issue. thanks chris....
