Default My ultra cost effecient evac sysyem

What are the disadvantages of using a stock style pcv valve in the valve cover connected to the big vacum port at the back of the carb,as opposed to a header evac system,or just venting the crankase with breathers in the valve covers? (very mild sbc)

the advantage of breathers or header evac over pcv is you arent feeding blowby back into the combustion process. header evac over breathers is that the header evac is supposed to pull vacuum on the crankcase up to 3" is what i've heard, and improves ring seal. dont know how much it really does but thats the theory.
