For those who have used the GMPP LSx cast aluminum valve covers (#25534398/25534399), do these have a provision for the hose connection(s) at the intake manifold side? The description I've found at various sources doesn't say. If not how did you modify to provide for the hoses?

I figured I'd be drilling/tapping 1/8"npt with 90 degree elbows unless someone else has thought of alternatives. The cast aluminum isn't that thick and the 1/8"npt is a coarse thread.
Another option: the LS7 valley cover with integrated PCV (2.5mm orifice), a catch can and a breather cap for the R/S valve cover. That's how I have mine set up right now (with MTI Racing valve covers)...

Sounds like a good plan. I would, however, go with a 1/4" NPT to keep the I.D. a little larger. A little dab of JB Weld on the threads wouldn't hurt either.
Do a search over at Summit for a Spectre part #5946. It's a chrome version.
