pcv making idle rough?

the plugs and wires are correct...have checked them 10 times if not more...i tried a little test to see if they were all firing...drip water on header after running it for 5 mins to see if they were hot and they all were...and yes i put a new carb on it as well. as far as the dizzy yes it changes the sound but have aligned it to where it sounds the best it idles rough and when i give it gas it runs rough then i let off the gas and it sputters and dies
