1972 FORD V-8 GAS (use "Lead" or not)

Little help.
I bought this 1972 FORD and don't know if I need to use the Lead add in? Theres no catalack con-verter.
If I use the lead Add in,And don't need it will that hurt the motor?
Or by chance if I don't use it and need to will that hurt the motor.
Any input would realy help! thanks

no you dont have to use a lead additive, lead was used a long time ago to reduce engine knock and has also been said to offer some lubrication to the valve seats but it was minimal at best over the years the manufactures started making their valve seats out of harder materials to where they last longer whether it had anything to do with the removal of lead from fuel who knows, it is likely just do to better technology, a truck this old has probably seen several engines in and out of it anyhow and is already has had hardened valve seats installed due to engine rebuilding.

Most early 70's cars had hardened valve seats and should work fine on unleaded fuel.
