I don't mean to thread-jack but I have a Victor 5.0 that I am using in my new combination. I have a couple of q's. It's meant to run with out the egr spacer right? Also, do you like it? I normally wouldn't run such a short runner intake but I'm going to br running a really big blower so I'm thinking that I'll be compensating for the lack of RPM the intake was meant for. I just love the air gap design and the access to the engine!!! Anyway, the guy I got mine from drilled the back of the intake and put a nipple in it....I'm assuming that I should run a vacuum line to it. I'll send you pics if you want. That might be one way to go. The other alternative you have is an evac system- morroso sells one for $80. It vents the valve covers right into the exhaust.
