Looking forward to the performance aspect (and motorsport vibe). Efficiency? That went by the wayside long ago. This project is my undoing with respect to efficiency. I spent the better part of a week learning to hammer and dolly. It was all worth it. The perfect sound of a 'tink' when the metal moves just like you wanted and slowly becomes smooth to the touch...good stuff.

It is good to know that there are options available for different head setups.
