Let's see some cool evac systems.

I used a bolt-on -12AN bulkhead fitting that I modified to fit in the valve cover under the sheetmetal baffle that comes on the Mopar Performance valve covers (baffle is not pictured in last photo). I cut it to clear the rocker arms and the baffle, drilled a bunch of holes through it and then ran it to 2 -12 AN single fitting Motion Racework's catch cans.
