Hello Karl,
There are several things you might consider also replacing.
1. Replace both heater hoses at the back of the cylinder head to the
fire wall.
2. Iim not sure what configuration a 86 motor has? But consider changing
the thermo time switch & the temp. sensor.
3. Replace the vacuum hoses for the wax thermostat.
4. Inspect the intake bellows.
5. Consider at this time if you would like to install a flame trap kit.
a. This extends the length of hose from the oil trap on the motor
to a location that you can reach the flame guard easily.
Yes, replace all the intake gaskets. It's cheap insurance.
