| dude, if the head is alloy it already has hardened valve seats so you can run it on unleaded, but if you want to be on the safe side use an additive like an upper cylinder lube and lead suppliment in your fuel. With the lube you can only use premium but thats ok because old cars were designed for a higher octane fuel(standard unleaded has a level too low) and thats the best at the pump |
