I am pretty sure I could do it a little better now LOL. The original intent of the question is to see what some simple work can do. Kind of a time vs. benefit thing. The big picture always been to run aluminum heads. As many have said, and the calculator does not lie, fully rebuilding iron heads gets into aluminum head costs pretty quick.

Still researching the convertor thing. With the amount of cars that I have, and my wife and I commuting together (she is not a fan of old, smelly cars) I am not real concerned with drivability, etc. It will be an occasional weekend warrior car.

The gears are going to stay for now.
