Thanks for your reply. I tried to respond with a link to where I got the information, but it is being moderated since I'm a new poster. Here is what I found:

1955 and Newer: Closed crankcase (PCV, Sealed filler Cap, Air cleaner to C/Case hose).
1966 and Newer: Exhaust Emission Controls (Air Cleaner, Carburetor, Distributor, Air Pump, EGR,
Vacuum valves, ECU, Sensors, etc.). Pretty much everything related to the operation of that big air pump
we call an 'engine' is considered an emission control device. Your car, when it gets it's BAR number has to
have all of the STOCK devices intact and operating. You cannot change carburetors, air cleaners,
distributor, etc. STOCK. I can't stress this enough.

My crate motor came with push-in style valve cover breathers. Do I need to replace them with the type that use a hose going to a catch can?

Thanks,
Kent
