Picked it up with a couple of minis but it's got me stumped
Why dose it have those pipes going in to the head, I assume it's into the water jacket.

Small looking valves but I can only find numbers behind the thermo housing and under the rocker cover near cyl 4 bypass hose.

anyone got any ideas and how to I tell what it's off

Those pipes are part of the air injection system that was part of the emissions control on late clubmans ... 77 / 78

It is off A Mini that was originally fitted with pollution control equipment, You can put some Grub screws in these holes, This is NOT suitable for a 1275

So those pipes go into the air ports? is that the inlet or exhaust?

They go into the exhaust ports.
If you want to plug the holes in the head the thread is 7/16" UNF.
Grubscrews this size are expensive in most places.
A cheap way to do it is screw old seatbelt bolts in and cut them off flush.
Or make them grubscrews, by cutting their threads to length and putting a slot in with a hacksaw.
