3 angle valve job

I was just wondering how much difference the 3 angle valve job would make on the motors and is it even worth worrying about. The way I read it was you did it to the head and not the valve correct me if I am wrong.
Thanks
 
Valve seat only and yes it helps a little. Just don't over do it or it will hurt power. Fine line between what helps and what hurts, if you don't know how much it's best to leave it alone.
