This will explain it better than I ever could. 
They go in the lifter valley between the cyl head and the lifter and actually provide extra spring pressure on the lifter to help it maintain contact with the cam.

I agree. Just make sure you know what you're doing. Don't think your LS1 is going to put out twice as much hp as tq if you rev it to 8,000 like an import would. If you're gonna rev higher you'll need a bigger cam to actually make power in those rpms.
Shameful.... I know... But he asked.

What cam are you looking at? Would think that beehive springs and Ti retainers should keep mass low enough that the rev kit is a bit overkill - unless you are running a lot of lift.
Sounds like a monster - hope this ain't your daily driver.
Problem with a setup like this is getting the right springs for the job once you've put the rev kit in. You'll want something that can handle the lift, but you'll no longer need the high pressures. You may just be able to dump the inner springs, but then does the outer still have enough pressure to suffice?
Also, if you decide to swap cams down the road, your heads will have to come back off to get the rev kit out.
