Our Austin DS5 Aluminium Cylinder Heads are the best and only ones on the market!
After 18 years of successfully producing Austin-Healey aluminium cylinder heads, we are pleased to launch the Austin DS5 version. We went back to the drawing board and started with completely new CAD drawings to ensure perfect accuracy, matched profiling and perfect detailing. From these drawings we fully CNC machine each head in our own factory - start to finish.

The Austin DS5 6 cylinder 4.0 Ltr engine, is very similar in design, to the 2.66 Ltr 4 cylinder Austin engine used in the Healey 100 and A90 Atlantic. The DS5 was used in the Jensen 541, 541R and 541S as well as in the early Jensen Interceptor.

The Fast Road Heads come fully assembled with our Austin-Healey valves, guides, springs, top caps etc. and are supplied with rocker and manifold stud kits. 
The head is directly interchangeable for the Standard.
