Leading A-Series engine specialist since 1981
Unlock the performance potential of your 1275cc A-Series engine with the MED Road Competition cylinder head. We have modified thousands of cylinder heads to this specification over many decades, regularly updating the design for the highest quality product.
The Road Competition has been developed specifically for use with single or twin SU carburettors, but can also be machined to suit an SPi or MPi Mini.
Enlarged three-angle valves are manufactured from 21NS stainless steel forgings, plasma nitrided for extra strength and wear characteristics, and installed in our own high quality bronze valve guides. The combustion chambers are expertly re-profiled and the capacity optimised to gain the correct compression ratio for your engine.
Final assembly is completed with MED road-spec double valve springs, triple groove collets and valve retainers. The head can be supplied to suit 9-stud or 11-stud head fixings and painted in a variety of colours, ready to fit.

We aim to deliver within 20 working days from the initial order, however during the race season this can vary with demand. Please contact us for the most accurate lead times.
These are now only available on an outright basis, based on a brand new MPi Mini casting that can be adapted to suit earlier engines.
