Bob is correct. The tubes from each cam cover to the air horn is for the filtered purge air to the crankcase.

I believe the catch can should be installed into the line between the PCV's & the plenum. That's where oil in the plenum comes from, sucked up through the PCV's vi the PCV system vacuum source. Here's a drawing I made to show how we are going to do it on the Raptor TT system.
