3" by 9" ? 4" x 8" (the overflow calculator on reefcentral says that i need 9inch linear overflow length for 600gph..but i dont know if that value includes the teeth or just the gaps)
I'm most likely running a 1 inch bulkheads (so 600gph) as my drain, and for my return i'd need a 3/4" bulkhead ..so taht means my largest drilled hole should be 1 3/4" inch ?
Help please, and thanks in advance. -- I asked 3 times on reefcentral, and my threads get buried in no time! Might as well try here as well!

I think you should strongly consider a Herbie style system as opposed to the Durso. I've been doing lots of reading/research on this, and it seems like a much better system (quieter, safer, etc.)!
For the overflow, I honestly think it depends on what type of aesthetic you're shooting for. I'm personally more inclined toward a horizontal Calfo/"coast-to-coast" type overflow as opposed to an in-corner vertical overflow. That combined with the Herbie is "bang on"....as my British friends like to say
In addition to looking better (my opinion), it also skims the surface of your tank like a mo-fo. And there's really no such thing as over surface skimming.
Not sure if someone has already mentioned this, but you don't need teeth on your overflow. It reduces the surface skimming area dramatically.
