Eliminating the pcv makes the idle circuit afr way too rich.
And makes the throttles too far open at idle. Too muich idle transfer slot exposure at idle.
Fix the valve cover baffling and PCV hole location so it does not suck up oil.
Most of the pretty aftermarket valve covers are designed wrong.
When you correct everything you fubared up the plugs will run clean.

It could not have been explained more correctly.
