Mini Cooper MG Midget Sprite

Stage 2 12G202 Cylinder head

Now a rare item

Fitted to 970-1098cc Mini Coopers

_______________________

Upgrade your 998 Mini, MG or Morris Minor for performance gains.

Large inlet valves 1 5/32inches (29.36mm.)

Chamber volume less than 26.1cc., which will give useful increase in compression ratio.

The bigger inlet valves, better porting and chamber shaping to minimise valve shrouding will, together with manifold changes, increase torque and horsepower.

Plenty of head face material to allow further machining/skimming for even more performance gains.

However if you choose not to upgrade further, this head is ready to fit, all valves/seats refaced and lapped.

Head face skimmed for true surface in renowned machine shop. Combustion chambers and ports cleaned.
