Valve covers fit perfect and look great.
The OEM valve covers have baffles in them no PCV. I do not remember if these covers had baffles. The PCV system is built into the pipe going into the intake on an LS3/L99 motor. I have a catch can/oil separator installed on mine to keep the oil of the intake.
Add an oil catch can . Hooks up to the pcv valve and your intake. Its what most people do. Probably have to clean your intake out after you do this to get the extra oil out from a failed pcv valve
