Well it depends on how smooth the surface was before you lap it. If the surface is already smooth, then lapping won't do much, but if it has imperfections, then lapping can cause a big performance increase. There is a risk that lapping will cause problems with the cpu. However, as long as you are careful, it is a small risk. Just don't take off too much metal.

If your cpu is not flat then lapping may help.

If your cpu is flat then lapping probably won't help.

Use a razor blade to test the surface.

The amount of sanding you'd probably have to do to get through the entire IHS probably makes it mostly safe. Generally, the biggest benefits come from having both the CPU and heatsink base lapped. I lapped my old Core 2 Duo E8400, and saw minimal drops, but the heatsink base wasn't lapped, and the sensors were also messed up to begin with. It's generally hard to mess it up though.
