Hello.

 

Just wondered if we have any interest in my 12G940.  Its 11 stud,  fitted with 37mm inlets and 29mm exhaust valves, 21cc chamber volume comes with ARP rocker studs, double valve springs and standard rockers.  Around 2500 miles ago it was refreshed with new valve guides and mpi stem seals

 

Please note this is still leaded due to the 37mm inlets, was running on my 1380 cc NA engine

 

I'm told this is stage 4 but have no written prove who originally worked on the head.

 

Not sure how to post photos now.  but any questions please ask

 

£300 collection from Norfolk

Sorry for the slow reply.

 

It looks like It can be posted insured for around £20 depending on the exact weight.

 

I will post some photo's up

I believe 12G 1805 by the thermostat indicates a Coopers S MK 3 Head so it will be an A not an A+
