Ron,
The first thing we checked was the spring, and keeper and were o.k. the heads are edelbrock and were on the engine before, valves and all. I can only assume the valves were the right length from before, but there appears to be no damage to valves just scratches and pitting on the aluminum recess in the head. I am wondering about the integrity of the new crank now, this kind of malfunction has to put a lot of stress on it! the rod was bent at about 70 degrees and #3 piston was disintegrated.
