At higher RPMs there is little vacuum and with high compression, "Let's go Charlie" speeds, there is blow-by that will occur. Valve seals and rings seal almost all, but not all.
I get blow-by that causes the breather to shed
oil onto the valve cover. Makes a mess. I hit 8500 RPMs and I know there is bloe-by.
On top of that, roller rockers sling
oil all over. If your baffles are open-ended, they are going to have
oil slung up into the baffled area.
Keep your PCV system. My compression tests were all in the 180 to 195 range and the engine makes plenty of HP.
Just my opinion.
