Muzzys says 200 HP
Wayne Lawson says 260 HP (i think)
just make sure AFR is good and you arent getting too high with duty cycle
you may want to increase fuel pressure?

I would bump fuel pressure or upgrade the injectors just to be safe.

no need to bump fuel pressure...
with the .032 jet, the injectors seen a max duty cycle of 85% which is well safe IMO...
the .028 jet was 83%
even at .032 we tuned it rich,so you could prob safely put a 34/36 jet in ,and still have enough fuel
