PCV- Good or bad idea for a performance engine?

when i bought my dodge dart it only had two push-in oil breathers. The first thing i did was install the old chrome direct connection valve covers with one pcv an one push-in oil breather. The previous owner was riving the car on the street and track. I drive the car on the street, i havent got a chance to race it yet but i will soon.

The 440 engine didn't leak oil before & it doesnt now
What did i do performance wise? Did i lose horsepower or did i gain horsepower?

this is what i removed:


This is the engine now:
