I switched my 352 to a PCV system a number of years ago. It has made an incredible quality of life change as there is no exhaust or smoke in my engine bay or car cabin anymore. It all goes out the back. My engine is fine its just a normal process with a draft tube set up. There were a few ways to go:

1. Get a new plate with a nipple for under the carb. Then run a hose to the road draft tube and attach the hose with pcv and a rubber gasket that fits the PCV valve in the middle of it.
2. You can get a new oil breather cap with a nipple - then do the same as above.
3. Change the Carb to an Edelbrock with 600 CFM. They come with a nipple on the front. Then do the same as #1.

Just make sure you get the right size PCV valve and a rubber gasket that fits the draft tube.
