This head has been refurbished with new MG Metro inlet valves (36.6mm), new inlet valve guides and new stem seals all round, it keeps the standard springs. The inlet valve seats have been professionally cut, blended and the head skimmed. The exhaust seats have been re-ground and all valves lapped in. The ports have been sympathetically ported and the standard rough cast finish in the inlet ports, exhaust throats and combustion chambers has been ground smooth and polished. This is an MPI head but could be easily converted for use with a carburettor Mini. It does of course have the hardened seats for unleaded.
Price €320
I am willing to buy your old head in exchange for €50 and I can provide a fitting service at a small charge to cover gaskets and coolant.
Please PM me if interested.

The process of polishing a head involves the full strip down of the head including the removal of the inlet valve guides and it is also impossible not to touch the valve seats whilst grinding and polishing. This means that new guides need to be pressed in, all seats need refaced and a head skim is the minimum amount of machine work that's required in order to maintain quality. So you could save a few quid on valves if the original ones are still serviceable but essentially that's the only saving you could make. So unless you've already got big valves fitted why not go for the upgrade.
