H, To explain....(kinda can of worms)...
Big Cam + PCV
If you don't have enough vacuum, the PCV will not move up into its "normal" idle position (causing a lean condition. i.e. vacuum leak)(causing more fuel metering problems @ idle). Kinda contradictory to my first post. When running @ speed the pressure in the not all flow through the PCV, More will go to the atmosphere.
Breather to arrestor
If the engine is sealed (no fresh air source for the blowby to flow out) + (excess blowby) then run the hose to the arrestor so the blowby gasses go to the carb and nowhere else.
To make it run properly (albeit more harmful to the atmosphere), Do as SD013 says and run straight breathers.
