I've been conflicting advice concerning my 425 buildup and its use in road racing/autocrossing.

One of those is the use of a PCV valve. I've been told by a person that does a lot of circle track racing that I don't want to run a PCV valve. He said I should run a valve cover setup similar to this:

And a Stef's Direct Crankcase/Oil Pan Vent setup:

Any thoughts on this? The car is being built to run on the track but will be primarily a fun street car. Probably 80% street and 20% track.
Thanks for any input.
