Thanks Anew - You are right !!, I'm running an earlier set of heads that doesn't have this hole/boss on the head - MYSTERY SOLVED !!. Luckily I was rummaging through one of my cans of bolts and found a small bracket that I can bolt on the exhaust manifold that should work just fine to connect the rod at the right location and height. Thanks to all who contributed - no more hair pulling.
