These are some shots of what I did to set up the double-front Panheads for the Sword of Damocles engine. On the "rear" head, I relocated the exhaust port to the left so it would clear the front head. I welded up the old tract and re-ported the head to flow out the new exhaust manifold. For the intakes, I built the manifolds onto the heads with flanges for the carbs. I had to make the aluminum elbows from straight tube then machine flanges and weld it all up and blend it out. Inside and out. Runs great.
