pcv question

[69heavychevy]

Hi everybody. the other day i got the bright idea to get rid of my pcv and put a breather cap in its place. on the carb were the pcv hose was connected i put a little tuner breather/paper filter. now the truck seems to idle really high obvouisely, you can really hear the carb sucking in all that extra air. it almost sounds like i have a blower. anyways my question is wether theres any advantages to running a setup like this. the motor should still be getting vented properly through the cap breather on the valve cover right. one thing i noticed is that my truck is a little harder to start, i have to give it some gas so it wont stall.
