Run the math, and you'll see it doesn't make sense. Intake and exhaust valves are about $40/each. Factor in the cost of machining and time to replace the valves and it's still cheaper to replace the valves every 50K miles (a conservative estimate) than toss in a buck or two of additive every fill up.

Has anyone been using the lead additives/substitues in their loops? A friend of mine is replacing valves on an old truck that he ran on unleaded and is now worrying that he doing his Eldo harm. Is this a cause for concern. I have run my Eldo on high octane unleaded for years and have had no problems.
