Degree Wheel use

[Marty Bricker <mbrickerusn@xxxxxxxxx>]

OK, once again showing my ignorance, do I need to use
a degree wheel when rebuilding my 258 engine?  Neither
the TSM or Haynes mention using one but I see them
being used on 2 Guys Garage, Hot Rod tv, etc so I'm
confused.  If so, what kind should I purchase (JEGS
has several different ones listed...the only place I
could find one).  Hopefully it will also come with
directions for use...!  Thanks.
Marty
