The main problem you have to look out for is extended long high speed drives or long range towing. Under these conditions the exhaust seat takes a lot more stress.If your 56 is running ok, go ahead and drive it. On the slim chance you burn a valve or seat, install the hardened seats then. I doubt you will have any trouble with it though. joe frega wrote: > Hi everyone, > > Today's question: > > Do I need to use a lead gasoline addative in my 56 Belvedere, 277 Hy > Fire?
