PCV delete ideas/vent with catch can

Drag cars use a scavenging system whereas they install an agled bung into the headers and is basicly siphons the emissions from the crankcase....it works well at full throttle......pcv system was intended for street use.....
I have been looking for someone to say you don't need to run a pcv System. A mechanic took mine out of my 318 and said I don't need it. ( I have a breather on each side) He also built and races a 9 second car so I Figured he knows what he is doing. He's been working on cars for 35 years or better.
