Power heads, flow rate and position question

[frankieg2]

I just bought from ebay two power heads, Koralia EVO Rated 750 gph, My questions are is this too much flow rate for my tank and where should I position them, I'm thinking to put them about 5 inh. down from the top on either side of the tank pointing at each other.
I have a 72 gal. bowfront FOWLR and using a Mag 7 return pump, 100 lbs LR and 80 lbs LS

That sounds like a plan. I have mine bouncing off each other and towards the rock. I have some pretty good circulation in my 55g with the 2 750's.
