Folks
I am building a head for a race mini and I need to lower spring seats to suit new springs, does anyone know were i can buy a valve spring seat cutter from. I have searched the web but can't find anything that is the right size.

Any help would be appreciated

I know what you have in mind, the flat cutter works similar to a tap reseater but is mounted on a pilot. Not seen one for years.
It is possible to make a HSS single point tool to put in a bench drill, but IMO would be easier to take the head to a machine shop and let them spotface the spring seats in a milling machine.

They don't keep them at their local agents but you can order direct from the states

Do you know what the crane cams part number is, can't find anything the right size in their online catalogue.
