Crank case Evac kit and Valley cover?

Anyone tried this?
Friend of mine doing a build was curious if it'd work, since it's a cramp for room on the valve covers with the coil packs and such. I can see why it would, but also maybe why it would not. I'm still fairly new to LS1 stuff so I figured I'd ask here for a solid answer.
Basically mount these under the intake into an after market valley cover, the same as you would on valve covers on an older motor.

"Reduces crankcase pressure throughout entire rpm range for increased piston ring seal, reduced intake charge contamination, and fewer oil leaks
Track and dyno tests prove increases in engine performance
Includes 2 each: Oil Separators/Breathers, Breather/Filler Cap Grommets, One-Way Check Valve and Weld-In Nipple for header collector, use with 5/8" dia. hose."
Then they plumb from the breathers down to the headers.
Also, who makes a nice smoothed valley cover for the LSx stuff using Victor jr/GMPP intakes?
