Leading A-Series engine specialist since 1981
If you're looking to turbocharge or supercharge your A-Series engine, we can machine a high performance cylinder head to suit. The combustion chambers are specially profiled to make the most from your engine, with capacities from 18 to 27cc. We've machined hundreds of heads to this specification over many years with great success.
High-flow race valves with single-groove steel caps and collets allow for high power outputs to be achieved, and there are a variety of options to tailor the head to your requirements, as listed below.
Final assembly is completed with MED road-spec double valve springs. The head can be supplied to suit 9-stud or 11-stud head fixings and painted in a variety of colours, ready to fit.

Please note, these cylinder heads are machined to order - once you have purchased this product a member of our sales team will contact you to finalise the specification and advise delivery.

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.
