E30 Zone

Does anyone know of a good place in/near Colchester, Essex to get my 731 cylinder head refaced/resurfaced in readiness for fitment to the eta lump I've finally fitted to my old girl?

Or should I just set to it with a sanding pad and then polish it like I did to my Sunbeam Alpine?

These E30 specialists near you may be able to help.
