It is a low compression motor. Your numbers are fine for the age. You have to decide if you want to spend the $$ to refresh your old gal. On the cheap side, your looking at about $1,600.00-$2K depending on once the head is off an torn down. Block work, and hopefully pistons arent ovaled.
Do a gradual seafoam or ring free treatment via the tank. If you haven't done a engine tuner treatment in many years then the shock of breaking away carbon deposits could lead to more problems then you want.
Although we are big advocates of normal maintenance if the motor has been neglected (not by you) a sudden shock to the iternals can cause issues, so I recommend a gradual approach like eating Oatmeal everyday for 30 days .
