Scott hit the nail on the head. If you have the multi-leaf and staggered shock setup and you still get wheel hop bad enough to annoy you, the "Lakewood" style bars are supposed to correct the problem.
I have corresponded with a guy on the Classical Pontiac board who converted to multi-leaves on a dual factory traction bar '67 setup (non-staggered shocks) and he swears by it. Says it totally elimitated the problem.
Me, personally, I have obtained a complete driver's side factory traction bar setup to go with my original one. I will stick with the mono-springs and the non-staggered shocks and see how it works out.
BTW, for those of you interested in turning your 'Bird into a corner carving machine - here is a 1st Gen Camaro site with great Suspension forum sections. The mediators are people who are into autocrossing big time.
