With the desireable 12G940 castings becoming hard to find, this may be the best option for serious performance from your 1275 or bigger A-series engine. This new casting does away with the primitive shared intake-port design of the standard head, and results in a cross-flow cylinder head with much better performance potential like most modern performance engines. It puts the intake out in front, getting it away from the heat of the exhaust. It allows mounting a pair of 40 or 45 DCOE Weber side-draft carbs right onto the head, AND it can all fit under the standard bonnet!
The head is supplied with the standard 1.3" intake, and 1.15" exhaust valves, and uses the compact NGK ER9EH spark plugs.

For ultimate performance, this head is cast for large bore engines with the valve-spacing increased to allow much bigger valves without the expense and complexity of using off-set guides. It will accept 1.44" intake valves and 1.21" exhaust valves buy simply cutting back the seats and opening up the valve throats. It can have up to 1.48" intake valves, if the exhaust is kept at 1.15", matching the full SCCA race-spec heads. There is ample material to surface the deck for high compression engines to go with the enormous valves.

In addition, this head is the best choice for tuners adapting modern fuel injection systems as the individual intake runners allow precise fuel metering and control not possible with the stock shared ports. Stay tuned for a stand-alone port fuel injection system that mounts compact throttle bodies instead of huge carbs! That's how the Fuel Injection Mini SHOULD have been! Also fits Sprite and MG Midget .
