5 Port Aluminium Cylinder Head

Working to original drawings, these brand new cylinder heads are designed to the original factory specification. When fitting an aluminium head, you must run with 100% antifreeze/summer coolant that contains the correct inhibitors to prevent corrosion and electrolytic reaction. We recommend you use new hardware, nuts, studs  etc... when fitting these heads to ensure a good fit. All our 5-port heads are supplied as fully machined bare heads, with bronze valve guides and lead free valve seats. Heads can be modified to a higher specification.

Please note: Please ensure the valves clear the bore when fitting. Valve pockets may be required on MGA if valves hit the edge of the block.
