New motor fuel pressure

Awhile back I had a post on first start up of modified motor. It is a 454 with 6395 and stock bin had injector flow at 67.5 and Dave suggested lowering 2-3 lbs to trick the system for start. The plan always was to install an external regulator at some point and putting the motor back in it require some changes to fuel line routing so just got with it an installed the external reg and braided line the way I wanted it later. The stock system runs about 28 lbs and I thought if I upped it to about 32 that should richen it up enough for the start up. Do you think that is enough?
