Now that you are modifying your engine to be more "streetable," you might want to revisit the PCV issue.

May be worth considering.
How did you configure it on the BT intake? Since I don't have a vacuum port on my carb, this intake may make things easier, either by using the vacuum port on the intake itself, or by using a carb spacer with a vacuum fitting (I have more vertical room now).
Can you go PCV in the passenger side valve cover to the vacuum port on the intake, and then a breather with a tube into the air cleaner base? Is that right?

The tried and true method, which is what I have in the pic below, is to have the PCV valve in the cap on the rear passenger side valve cover, the breather cap is on the front driver side valve cover. Then run your vacuum line to whatever it is you happen to have available. Mine required a small bit a fabbing because of my Turkey Pan base. Nothing big. Because of the rotation of the engine, you almost always see the PCV on the passenger side of an FE. Baffling of the cover is important, otherwise you'll suck up more oil than you might think. I've got a pic of my VC baffling. Again, nothing fancy, just a little metal welded on and clearance so the rockers don't whack them.

Thanks Patrick. So I'm clear, do you just have a breather cap on the driver's side? Without a hose to the air cleaner base?

Correct. The only thing in the driver's side VC is a breather cap. No hose. It is an "Open System" in that it draws fresh air from the atmosphere, not from the intake system.
