Rocker Arm help

Is your pattern biased toward the pushrod or the exhaust ports? Whomever has the B3 shim kit, post a few pics of what it is. I can assume if you change the valve length your going to change the pattern, a longer valve/lash capped valve will move pattern out. Also the Mopar cast rockers may have a slightly different dimension running a straight edge across the adjuster/rocker tip contest to the shaft centerline.
