Doug's Headers Crankcase Evac Location

Hi Guys, I'm hoping you can share some experience with where you have located the crankcase evacuation system on your Doug's D453 headers. I am installing these headers on my 360 '70 Duster drag car. I am hoping to see where you have installed the evac system in the headers to create the most clearance and best hose routing. I am thinking perpendicular to ground on the top of the collector right at the end of the primary tubes would work, but will that interfere with the transmission or starter at all?
Any pictures or advice is appreciated. Thanks!
