I don't think you're going to find too much hardcore info on specifically strengthing bi's. There isn't alot of reason for it, at least in strength sports.
Tri's on the other hand you'll find a ton, and Westside is one of the best.
If you're familiar with Westside practices you can just apply them to your bi's of course.
Basically you would need to do heavy movements at low reps, between 5 - 8. Now some people might say 8 is even too high for real strength training, but keep in mind that biceps movements are all pulling motions, and when you go too low form suffers badly.
Along with this I'd also change up the movements every 6 weeks. According to Westside your body starts to adapt if you continue the same routine for any longer.
But be careful, going real heavy on isolation movements carries a greater risk of injury.
