Those baffles are not for a pcv and wont work in the respect of keeping oil out of the vacuum line! They are for installing extra breathers!
You need a baffle that insulates the grommet and wont let liquid oil get close to the vacuum draw but lets fumes get to the PCV like a bottom vented box between the rockers low enough to be out of the oil cast off but high enough to be off the head surface! with those low profile covers it would be hard! They sure are "PURDY" though
You may have to hook up a catch can like mentioned earlier!
