I need a solution to this problem, any suggestions would be greatly appreciated. I have a 71 Lemans convt, with a 71 455 freshly rebuilt. It has the #15 heads. My plan was to use PY's ram air exhaust manifolds to taste up the exhaust system. I rec'd them and noticed there aren't enough mounting holes in the head to securely mount the exhaut manifolds. I can get 3 bolts on the pass side and only 2 on the drivers side. Not enough in my opinion. The end holes on each side head closest to the firewall are not drilled and tapped. Are there any retro fit kits out there that will allow these heads to be used with ram air exhaust? or do I take the heads off and get them drilled and tapped? Or should I go find some original 71 455 logs and put those on? Any suggestions would be greatly appreciated. Thanks j69
