Yes, I use PCV connected to the carburetor base as well as the Pan Evac (both).

When choosing where to mount the Pipe in the Header Collector, keep in mind that the Check-Valve and a Hose need to be connected to the pipe end. If the Pipe points toward the ground you might have ground clearance problems. If you mount the pipe on top you may have chassis clearance problems. Before you remove the headers, look at choosing the best mounting location.

Generally speaking, to have a good straight hose connection it is good to mount it on top of the collector or offset top to the right or left for good hose routing.
