Performance PCV valve part numbers?

[WCMachine]

A member posted some GM PCV valve part numbers that work well with large cams. I can't find the thread that had them.
Anybody know?
Also while we're talking PCV, any reason why a small K&N type filter can't be used on the inlet valve cove instead of it being plumed to the engine air filter?

I find the Wagner adjustable PCV valve to be a great solution for any application.

Crank case air filter was just a breather cap on a valve cover for many years. I'm not sure when or why this was plumbed to intake breather canisters. I'll guess EPA had a hand in that.

Yep, the Wagner is a bit pricey, but worth every penny.

Yes, the K & N will work great for that.
