Your opinion. I'd like to actually SEE that testimonial. Else, why would Ti valves and retainers be desired, only saving an ounce or so there?
My question would be: what is the expected longevity of these composite lifters? 10,000 miles? 50,000 miles? 100,000 miles? Any actual testing on that parameter?
