overflow problem

[pwnag3!!]

I purchased a CPR CS100 (800 GPH) overflow and received it today... the thing is they sent me a CS102 (1400 gph) instead... although im not being charged for the thing im going to use it!
ok.... would it make alot of noise of trouble if i put a ball valve on my overflow outlets? (it has two 1" bulkheads) would i run into problems?

Why not just run them both?

run a 300 gph and a 1400gph?
I guess i could.... i need to buy a new pump though... like a mag24
at 4 feat of head that runs at 2000 which i could just use a ball valve on that one
