maybe you can help me???

If its stock original its leaded gas if you can get it (only NASCAR Fuels, Avation fuels, racing fuels and the like can have lead), but unleaded won't hurt it if you drive it normaly and not under heavy loads or extended high speeds. use a premium grade not the lowest. This will help with the spark knock problem.

Lead was mainly used to control spark knock some say for valve seat lubrication but from all I've read on it there is little mention of engine damage using unleaded in an older engine under normal opertaion other than some guy said his uncle the mechanic said so type info.

If your going to drive it daily you may want to think about doing the exhaust valve seats. For the cost of a few hundred dollars you'll have peace of mind and no limitaions on driving.

This link will give you some solid info.
