PCV- Good or bad idea for a performance engine?

C130 - Thank you for a very well constructed and easily understood post -
(If the mods have a tech archive, your post should go in it!)

Now - my issue......

I have no blow by at idle, but due to poor ring fit I have some by-pass at high revs.

I dont like th idea of this blow-by going straight back into the fuel sytem - it MUST be polluting the A/F mixture to some extent...

BUT - I see all the sense in keeping the PCV system in place for "street duty"........

Any suggestions (the engine tear down is not due till next year and I have races to win!!)
