Corvette seems to think so,3 years now , for intake valves and rods ? Even though it weighs 2/3 that of steel, valve weight is less than 1/2 that of stainless aftermarket valve. This being a smaller 5/16 stem and beneficial weight reduction contouring, should equal 55 grams, once shortened. Ti valve should flow more air,(shape), tbd. Onward, roverman.
