[Dyno]

A few months back, David Reher (Reher-Morrison) wrote an article on how the use of titanium valves saved his customers money over the use of stainless valves. He claimed a longer life of all the valve train components (springs, lifters,etc.) and allowed a longer life between freshen ups. Not all combinations benefit from a higher RPM limit, but all could benefit from longer life of the parts. I would like to see them allowed, although I probably would not use them. Dan Zrust
