Hoyt, im not familiar with the LENS process you speak of, but it sounds interesting. Here is a comparision we can probably all relate to. How much different in cost would you think it would be to cast a 12 port Stovebolt head as opposed to the Sissell 12 port head. They are real close to the same size, and the machine work to complete both heads would be the roughly the same as far as time and additional parts like valve seats, guides, etc... Kirby has had his heads cast in a relatively low volume, but his unit cost per head to have them cast is reasonably cheap. So where does this extreme $5000 cost come from for a finished head with no porting come from that the Wayne Manufacturing Co. was trying to sell either the GMC or Stovebolt for. When a finished Sissell head is easily half that, depending on what level of completion you buy.
