There were a lot of variations of the pcv set up, even within the same model year depending on whether it was a California car or not. Unless you’re going for originality the only important thing is to set up a system that functions well.
That is the ideal set up. Ideally, you want the pcv vacuum source to be evenly distributed among the runners, or as evenly distributed as possible. Both to spread around the vacuum leak but also to spread around the crankcase waste product (including any oil sucked through) so it’s burned by all cylinders.
For the stockish/cruiser engine you’re building, the factory pcv routing to one intake runner would probably be fine. But if you want to move it, you have a few options. Aren’t you going to run an Edelbrock? The Edelbrock will have a large vac port designed for pcv. If not, you can get an aluminum carb spacer with a central vac port. If you don’t care about keeping the intake original you could also just drill a hole in the intake and add a port to a more central location that will draw to more runners.
You are going to need a hose from the valve cover to the air cleaner. For most of the years the hose ran to a nipple in the side of the air cleaner assembly and there was a foam/sponge strip in a bracket inside the air cleaner housing that acted as a filter. You can reproduce that set up, or you can run the hose to a nipple inside the air cleaner filter itself, so it’s only breathing filtered air and you don’t need an extra sponge piece.
Then you plug the hole in the other valve cover. This is the best functional set up. It creates a push pull system that freely evacuates the crankcase vapors under all engine conditions.
You’ll need some baffling system in the breathing valve cover. If you have the original oil drippers and/or baffles in the valve covers, those should work. Or get baffled vcs or add your own baffle. The important thing is to make sure neither your pcv nor your breather is sucking tangible amounts of oil into the engine. That is very bad. I assume you’re using the factory valley pan which has a very good baffle for that part of the system.
Btw, it’s been a while since we were last in touch. I finished my engine build about six months ago, so if you ever want to borrow any tools, including those ridiculously specific engine building tools that you can use only to perform a single task, just let me know. I also have a variety of leftover parts I didn’t end up using, like extra crank keys, block/head plugs, gaskets, studs, fasteners, and a whole grab bag of other random stuff. Shoot me a message if you need anything as you complete your build. You’re right up the street from me, iirc, and I might have just what you’re looking for.
