1. Torque the head (50#-FT) with the engine completely cold using the proper tightening sequence. Do this before each time you run the engine. At least 10 times. This is to allow the head gasket to completely compress and the head studs to stretch.
2. Do not use synthetic oil use a straight 40W oil that has an anti wear Zinc compound additive. 40W Valvoline V1 racing oil is what I use. It has the Zn additive. You can buy the Zn additive and add it to a 40W oil of your choice.
3. Do not use more than 4-1/2 quarts. The oilpan always has at least 1/2 quart remaining after the oil is removed. If you put 5 quarts in it will get pushed out somewhere usually the rear main bearing area.
4. Do not ever ever ever put anything in the fill tube and make certain your fill cap sits slightly above the tube.
5. Install a 160 degree thermostat in the hose above the pump and secure it with a clamp.oil pan
6. Lightly tighten the screws holding oil pan, the return tube, and the valve cover.

Let the engine break in. It is not like a modern engine. It will take a minimum of 1000 miles before you will see it begin to have more spunk. Keep your speed at 40 and occasionally go faster and bring it back. If you boil over that is an indication that everything is very tight or maybe your radiator is not working properly.
Good success.
