You're right I do need to read more posts on this site which I find informative and enjoyable. Wish I had found the forum a long time ago. It's good stuff!
Now, I have seen alot of drag race cars running a tube coming from the breather on the valve cover down to the header collector. I don't know if it's a PCV valve, it may not be, but I know I have seen it many times. I think I even read about the purpose or benefit in one of the car mags. Something about the exhaust gas pulses helping to draw out crankcase fumes or pressure or something like that.
