    I have the same carb, gone over by John Osborn. He used 76 jets, with 46B rods, and BG secondary rods.

    Although my Poston catalog only gives advertised specs, but not .050 duration, I would guess that cam is similar to the TA 212. Larry's KB 118 is a bunch bigger.
    You probably should go a smidge richer than mine since you have headers.
    (P.S. Mine was set up by JO too)
