I am definitely with the others, keep the PCV valve in place. That is the one emissions device that is a good thing for the engine and prolongs engine life. One of the by products of combustion is water, among some other nasty stuff. All engines have some blow-by past the rings, so water, fuel and the other nasty stuff gets into the crankcase. This stuff needs to be pulled out of the engine to keep the oil clean as possible. Fuel thins the oil, water gets in the oil and creates a acid which eats at the soft bearing material in the engine. Keep the PCV valve, there are no performance advantages to getting rid of it, lot of advantages to keeping it.
And do not run a thermostat temp lower than 180F. Keeping the engine warmer helps engine wear and also helps the PCV system by keeping the nasty stuff in suspension in the crankcase so the PCV system can pull it out of the engine.
