Thanks Jerome!
For the new mechanic reading this, JMRacecars recommendation for tightening bolts in a crossing pattern is a VERY good habit to get into. It was one of the very first things I learned when reinstalling the heads on my '53 flat head Ford when I was 16 and I've been using it ever since. When the part is round, like a flywheel or a regular wheel, where you start isn't a big deal, just go to the opposite side on each subsequent bolt. If the part is a rectangle, the general idea is to start in the middle and cross diagonally for each subsequent bolt. Below is a sequence diagram for a Ford 4.6 Mod Motor that gives an idea of what I am saying; although, if you are doing heads, you should always check the sequence for your particular engine. The ideas is that you want the part to lay out smoothly onto is mating surface with no internal stresses from clamping the ends first. (Think of your part as being plastic and determine how you would bolt it on while keeping it as flat to the mating surface as possible.)
