Advice Needed Drag Racing w/ Cragar SS

I'm putting together a street/strip (mostly strip) '68 Valiant. 543 hp, built 747 torqflite w/ brake, Dana 60, 456 gear, mini tubbed with 325-60 drag radials and Caltracs. I'm wanting to keep it old school and I've got Cragar SS wheels that are direct drill 4.5 bp with 1/2" screw in studs. At this power level and leaving on the trans breake, is this going to be a safe rear wheel choice?
