I'd get the one with the vacuum advance. If you're not familiar with the HEI there is tons of stuff on the net to help you. Also, educate yourself on what the mechanical and vacuum advance does and how it's adjusted.

Here's a good site that you can look at but there are others just as good or better: http://rmcavoy.freeshell.org/HEI.html
