the metro turbo head head had standard size valves fitted supposed to the N/A mg metro which had a inlet (or outlet) valve 2mm bigger than standard.
The only difference in the standard head and turbo head is the valves are sodium filled to aid cooling/overheating.

you'd have to pocket the block to put a 1275 head on a 998

You'll also need to find out what the combustion chamber size of the head is. It'll screw yer compression ratio up if it is wrong.
