225 Bending Rods

I had this same problem on a 69 Dart I had. The problem was build up on the valve stem. Trying to run a mixture of old gas that was in the car and new gas. The valves would stay open, not close all the way. The piston would smack it and bend the push rod. I had to pull the head, completely disassemble it and clean everything really well. That fixed it. Oh yeah, had to clean out all the bad gas too. :oops:
