Confirm correct plug is being used. Confirm the operation of thermostats and poppit valve.--------------------Check that your ignition system is strong.----A good system will easily fire across a 7/16" gap or better.

NGK BU8H is the right plug for a V6 in those years.
All 6 are fouled? Check the ignition system.
Use the Premuim plus oil and 89 gas.
Check the oil rod adjustment.
Check the 2 PSI valve in the oil line.
