PCV Question

[dontlifttoshift]

It seems related so I will ask here. The fixed orifice is in both the valley cover AND the valve covers? When dealing with aftermarket valve covers do those hose connections need to be dialed down to that orfice size? A port in a stock cover measures .105", I haven't measured a valley cover port yet.

So I guess the question is this, when dealing with a stock LS3 with the stock valley cover and dirty air hose running to the throttle body, does it matter what is in the valve covers as long there is some source to get fresh air into the engine and that the air comes from the air intake between the MAF and the throttle blade?
