This guy has a really good site with engine rebuilding, valve jobs, and other usefull things:

I bought the Bug Me video and set it up in my garage while rebuilding the motor. I thought it lacked some things though and would probably not use it again.
Depending on your peppyness factor and what parts you already own buying a 1776 or something already built from Chico Performance or Serrano, both can be found on
http://www.thesamba.com , would probably be cheaper. I made up a spread sheet and found that I could not match the price of their 1776 motor if I was to buy the parts and build it myself.
