HEI 101? (hesitant about upgrade)

[sactoC10]

OK, seems that this upgrade/modification is a favorite among many for sure. My sputtering problems seem to be related to points, condenser and coil issues... and not fuel delivery related. My mechanical successes have been generally motorcycle related (dropped/swapped and engine, jetting, etc...) so I am fairly certain that I can do this HEI thing, but am concerned about making some painful mistake.

I have searched the forums and printed out some old threads, but would really like a quick step by step run down of the how-to's before I jump into this. Sounds pretty easy, but electrical stuff makes me nervous. Thanks for any help and references.
