This specification was the ultimate A-series, factory version, cylinder head. Developed initially by Daniel Richmond at Downton Engineering

This 7E7 is a very late, UNLEADED head with full face thickness for further machining.

Being a late unleaded head there is no water by-pass outlet, no rear of head heater outlet nor water temperature sensor drilling. Easily overcome by fitting the easily available later Metro style thermostat outlet fittings

Porting exemplary. Ports and chambers cleaned.
Valves triple groove collets
Valve seats checked and recut as required.
Valves cleaned, refaced and hand lapped.
Valve seals to inlet valve stems.
Perfect compression and long life.

Photographs show actual head offered and the extent of the overhaul work.

Studs, fittings and tuning/fitting advice available

Big valve heads, the best and cheapest power mod. for 1275/1300cc Minis. Can also be used on the 998cc. (Advice freely given)

________________________

Heads straight from cars or scrap yards often hold horrors as here,
and the valves.
The costs of repair/replacements can be many times that of your ‘bargain’
