Couple things,
People are saying a catch can, not sure what they mean by that, they do have a stock style setup with a can to catch the oil and you can drain this can
If the motor does not breath properly then it is a air compressor building up windage, windage is harder on rings and seals,
I like a breather box above the motor, at least 2-3'' above the motor,
the larger the hoses, the less chance oil will travel up the hoses,
stock hoses are 3/8 and can work like a straw pulling oil with them,
Running a 10 is a good idea, 12an is perfect,
Do not have any low spots that oil can pool or travel up the hose, if oil is in the hose you want it to travel back to the motor and the air to travel past the oil.
The Breather box i like 2 filters on the box, and baffles in the box,
Look inside the intake you will be surprised even when the motor is stock, how much junk is in the intake without a breather box
