My full quote was stainless steel exhaust and valves... normal steel anywhere from combustion chamber through tailtip might rust due to the high water content otherwise. Even if just the valves being stainless since the 80's is standard it's worth mentioning as a "handy tip!" since 1970's engines were in the discussion too and i'm not sure if they all had that then.
