I done a search on PVC setups and didn't find exactly what I was looking for to do with my '312 Merc. I have a Holley #4160, 600cfm-Four Barrel Carb. It has a Full Manifold Vacuum Port for Power Brake or PCV. I currently have it plugged off.

Can I drill a hole in the Right Valve Cover (next to the port on carb), insert a PVC Grommet, Valve and Rubber Hose to the Vacuum Port? Than go around on the drivers side and discard the original Road Draft Tube setup with a block off plate.

Will this setup work right? Does it matter where I cut the hole for the PVC Valve in the Valve Cover? 

I appreciate any and all comments on this setup!!!!!  Thanks~~~~~Ron
