Ah, a question that I have thought of since I started lifting weights. I would say, NO!
Now before other members want to start a fight, I was a competitive powerlifter, and used a pure Westside template. Max work, speed work, GM's, band, chains, reverse hypers, glute-ham, I used them all. Westside makes you a very powerful deadlifter, squatter and partial range of motion bencher.
A powerlifter wants to forget the lift, hit it and get the fuck out.
A bodybuilder wants to remember the weight, the pump, sore muscles.
Westside will gear your body to lifting explosively, which moves more weight, but does not recruit the most muscle fibers.
Benching in a Westside program will develop your triceps and delts well, but does nothing for your chest. Its a program geared towards a shirted bench, and works well for that.
The volume of work sets and the inclusion of speed work does nothing for a bodybuilder.
If you want to lift heavy, take a note from Mike Francois. Louie Simmons was a cornerstone in his career, and had him lift heavy, but not Westside.
If you want, do 2-5 rep squats, deadlifts and benches. But as a bodybuiler, you would want to include accessory lifts like DB presses, flyes, side raises, leg presses, leg ext., etc.

Once again, Westside works well for powerlifters/other athletes, but is not for bodybuilders.
