Lapping valves also increases the compression. When valves and the seats are pitted and carboned up, it really affects the engine performance.

Lapping does not increase compression. Will not remove pits, not used for removing carbon, and has zero effect on performance. There are tons of marketing ads pushing this crap and it's all a lie.
The only value of lapping is to verify correct contact location of the seat on the valve and the width of the contact after the seat stones and valve grinder have done their work. That's it. Everything else is bullshit.
