I wouldn't think the BPE (probably comparable to the Airwolfs on my 414) would be too large a port on a 10.5 360 with decent stall/gears and something like an RPM intake...not to the point where it would adversely kill torque on the street. It's not like its an 8.75:1 motor with 2200 stall and 2.94 rearend gears.

When the port is borderline too big move the cam up a few degrees to tighten up the Intake closing event/static compression. A lot of Chevy 350 guys would kill to have a 2.08 intake valve and a ~230-ish port that flows over 300 cfm. Might be overkill potential wise, but again, I'd rather have room to grow for not much more $$$.

I'd rather have a better head with room to grow (stroker down the road) than compromise, a slightly smaller duration cam is cheaper and will still make better power than the same cam with a more modest port. 360's generally don't lack for torque. if it was a 340 same/same everything else, I might back off the port cross section.
