Does anybody know how many gph the oceanic reefready 58gal overflows are rated for??

Title says it all

You need to know what size the drain hole is, which is probably on their website. If you want it larger, Oceanic can do that for you.

its a 1'' drain hole with 3/4'' return.

600 gph

Hmmm... I think I have more than that going through it now. I have been tinkering with my return pump wich is a poseidon ps4 that is now all the way open (besides being restricted to 3/4'' from 1'') with about 6 feet of head. Would this eventually overflow?

If your water level is constant, you are OK.

You can push more than 600 GPH through there depending on your overflow setup (standpipes, etc).. 600 GPH is a good estimate though on how much you should be. If its more and your levels are stable, then you are OK.

Well I just changed to this amount of flow so we will see how it goes I guess. Is there a meter out there somwhere for measuring flow?
