MG metro head (or the precursor to it) Basically it's a high performance head, very good thing to have... Big valves (33 and 28mm inlet & exhaust IIRC)

The hottest head for small bore engines is the 998 Cooper/MG 1100 12G295; for the big bore, the 12G940 head casting.

Rare as rocking horse kack, apparently.

Not my work - check out www.comp.glam.ac.uk/pages/staff/djcunlif/minis/minilib/review17.htm

12G295 is a Rover / Leyland / Austin etc. part number. I believe it's actually a part number for the casting so of course two heads with that number could bbe very different (valves, porting etc).

That's a great find. The 12G295 is the head originally fitted to the 998 Cooper in 1964.
To really make a 998 car go it's the only one to use as you can get the comp ratio right without risking grinding through an oil gallery. I'm just doing some work on one for Chris Spennewyn's Wolseley Hornet with slightly bigger inlet valves and a higher C.R. Lovely head to work on and easy to fully gas flow.
I've got two spare ones myself, but I think I'll hang onto them. One is off my son's 1967 Cooper 998 rally car on which we changed the engine to a 970 'S' unit. Never like the 970 - all revs and no real go.
