You bring up a good point about hurting the eng slow. If you don`t use the
eng to pull loads over extended trips you can get by on the unleaded gas for
a good deal of miliage before having any valve problems.
If you subject it to a lot of load they(the exahust valves) are going to be
in trouble shortly.
I know from experiance with a 77 454 that I used to tow a 30 foot trailer,
only problem I ever had with the eng was valves because of not being able to
buy leaded gas on the east coast in the mid 80`s. After I got back home I
never had any more problems. drove the truck untill 1994 and I still see it
around town.
