The heads can be rebuilt to handle modern fuel, and when the car eventually needs a valve job, that is what should be done anyway. I don't use my Imperials enough anymore to make it worth while, although when I do have work done I get the hardened valves and valve seats installed, mostly for the benefit of the next care taker after me.

In the ‘old’ days when we had 50s-60s high compression engines (’56 Plymouth Fury) that were supposed to use on high octane fuel, we always used ‘regular’. We did adjust the timing for that.
NOW, my query is; can we still use this method or must we buy ‘premium’? I am not familiar with the changes in the composition of today’s fuels. Does anyone out there have the facts on this? We do not use ethanol and are not likely to do so in the future. Would like to hear from those in the know.
