Okay, so what should I use?

I have a 1966 427 FE with dual carb setup 10.5:1 compression, medium riser.
I think I run okay on Chevron 93, but sometimes it burps alittle bit at start up, more if not really warmed up.
Should I use that lead substitute since I have honest pre- unleaded gas engine? What additives if any?
thanks,
Brett Bolte
