Keith was asking about the lifters, not the valves.

Both the valves and the lifters rotate due to the fact that they are 
slightly offset from the things they rub against (rockers and cam.) 
The springs might be part of it. That would work on the heads, but I 
think they would help on one side of the lifters and hinder on the 
other. I'm not sure about this.

I'd really have to check out the helicity of the springs and the 
locations of the rockers, valves, lifter bores, and cam lobes to be 
sure.
