Short list Dave....
First, make sure the coolent system is full and burped of all air.
A good CFM rated fan and a shroud if you have time.
Turn up the curb idle adjust to let the water pump move the coolant faster.
Keep it in the lowest gear to keep the rev's up.
Forget about the hole in the thermostat, it will be fully open anyhow.
Water wetter is a good idea too.
The hole is suggested so trapped air in the head/intake will pass through to allow coolant to take it's place when you replace the coolant (cold engine). After the system is full, and air burped out, it's done it's job.
Oh, and carry a rabbit's foot, lucky charm, cross your fingers and say a prayer
Have fun
