RE: Nothing.

First, there never were light-weight valves installed in any CJ/SCJ. Some 427s used a hollow-stem sodium-filled exhaust valve.

As far as horsepower gains using a light-weight valve...unto themselves they make no horsepower. The gain comes from the ability of the valvetrain to remain stable at high rpm so that if you have an engine that can rev to high rpm (like over 7k rpm) then they can allow it to run reliably at that level. In essence, you're allowing the engine to be all it can be, if I can borrow an ad slogan, by reducing the inertia of the valve's mass.
This thread, so far...
