You need a Pcv on one cover and a breather on the other cover.
If you have that you can remove the oil fill tube and plug the hole. IIRC a core plug is the same size.
You want to draw the air thru the motor from one side to the other so you remove as much of the fumes and moisture as is possible.
Well that answered my question. I was going to run my original 283 valve covers, with my pvc but I guess I cant.
