On a completely separate note. I will be glad to take those unrepairable and unusable heads and provide some level of cost recovery.

I will have John Marcella here in Detroit (do a Google search on him...) weld them up into something very, very usable and radical that you'll end up reading about in the magazines. There is absolutely nothing made from aluminum that he cannot repair. On some parts the cost outweighs the benefit - but a pair of Cammer heads would justify his time, and the level of work required on these simply pales in comparison to the stuff he often take on.
