Your 1972 454 does not have sodium filled stainless steel valves with rotators as far as I know, so it would be unwise to run unleaded fuel. I would add a lead additive. Do so more research to make sure I am correct, but I am 98% sure I am.

You just bought a 1969 442 what type of gas and oil should you put in it?
HIGH octane 10w-30 oil will work fine. also if your engine hasn't had the new hardened valve guides put in the heads to run unleaded gas you need to add a lead additive to the gas tank when you add gas to the tank, all parts stores carry the additive. Actually, that's kind of an old wives tale. Very seldom will you burn up the exhaust seats (not the valve guides) running an old engine on unleaded. If you run it at high RPMs or towing/lugging it a lot, then maybe. If you have the heads completely redone at some point, you could go ahead and have them installed for piece of mind. But 98% of the time they will be just fine. use sunoco ultra 93 toget the best timing advanc for max power

What is the difference between a 1972 Pontiac 350 160hp and a 1968 Pontiac 350 320hp. What would I need to change in the 1972 to make it the same as the 1968?
Better heads along with a different intake and carb. Bigger exhaust. A different camshaft. You would be the better off going to a 400ci.
