The red Loctite compound essentially glues the bolts together, and virtually eliminates the chances of them backing out. Be careful only to use a small bead - too much Loctite on the flywheel bolts can actually prevent them from seating properly. Ironically, this can cause the bolts to fall out later on - exactly what you were trying to prevent by using the Loctite in the first place!
The Lubro-Moly formulation is a bit thicker than others, which means it's easier to spread, and creates less of a mess. It comes in a 3.5 ounce tube, and one of these should be more than enough for a single 911 engine rebuild.
Plastigage provides a fast and accurate way to check bearing clearances. Plastigage is a special extruded plastic thread of a definite diameter with accurately controlled crush properties. The material is round, smooth and flexible through a wide range of temperatures. Extreme cold will make it somewhat brittle and heat will soften the material. However, Plastigage remains usable and accurate through all normal atmospheric variations of temperature and humidity in work areas where bearing clearances may be checked.
