I knocked out the front on the passenger side, and ran that to the carb. I only knocked out one hole per cover. I just used a 1/2 inch drift punch. I also used loctite on the baffle screws(I wasn't too confident in the way they screw in)
After re-reading this I think Nemo's got me covered. Nemo- Are you running a Holley carb that has the PCV outlet on the firewall side? So you ran your PCV to the passenger side? (your pic is good but doesnt show the pass. side very well)
