Head valve seat lip

[samotorsport]

What works best for you to remove this little lip around the valve seats in your heads ?



Have you done a special tool for this or you just do it with a high speed grinder ?

It doesnt matter much, because when you cut the seat the last 30-33 degree angle will make the flow shoot past it. But a nice blend in wohnt hurt.
