Lloyd and I put that letter together and sent it to NHRA. It was rejected and I thought that idea was gone. I have been told the aluminum head would always make less power, but they would be repairable. That was the concept/reason for the aluminum head. The other plus side is that the cylinder head experts would prefer to work on an aluminum head over the cast iron head.
