Check out how this guy cleans up valve seats!?

So, this guy puts a fine grit "paste" onto the valve, gets it seated back in the head, and spins it alot on order to "match the valves to the seats"... Has anyone seen this before? It seems like a reasonable idea.

here is the video, skip to 30:25 to see his method

Yep, good ol fashioned valve lapping. Usually when you install new valves or seats you want to do this.

oh cool. i'm self taught when it comes to engine work so im missing out on alot of old knowledge like that

Yeah thats how we did the valves in the small engines class in high school. I am pretty sure you can buy that paste at pretty much any parts store.
