The MSD gears come with detailed installation instructions. The installed
height is something they want you to get correct to within 0.004 inch or so.

I also got one of the Crane composite gears but haven't installed it... as
Sandy said, supposedly these are better than bronze gears.
The benefit (?) of a bronze or composite gear is that if there is a problem,
then you know that the cam will win and the worst thing that happens is you
have to flush a bunch of bronze flakes out of the bottom of the pan. If there
is a problem with the steel gear, then nobody wins. But at least the dross
that comes off that failure is magnetic so it will be captured by your
magnetic drain plug...
