10W30 with at least 900 parts per million of zinc and roughly the same parts per million of phosphorus. Quaker State high mileage 10W30 meets that requirement and is what I use. 

As for lead in the gasoline, your valve seats will have reduced life without it. Pouring additive into the gas every tank fill is a pain in the neck. I say just run the engine on regular gas with no additive until the valve seats fry (which could be thousands of miles down the road from now) and then do a valve job when that happens. I find that cheaper and easier than using additive. Just drive it until the seats fail on their own and then take care of it.
