Yes on the t-slot restrictors so here's my tune.......

.040 IFR'S lowered
.068-.070 idle bleeds
.026-.028 hi bleeds
.055 t-slots and .082-.088 jetting

You need a vacuum gauge to check for the best power valve and one that comes in as you crowd the throttle while cruising at a steady state speed........too high, rich too soon, too low delayed enrichment..........
