Hillman Imp race cylinder head

While the south easter gales continue to blow I may as well get on with setting up the new R20 fast road camshaft,I have called it a full race version but the R23 was designated that by Rootes Competitions Department,we are still looking at a camshaft that delivers power from 3200 rpm to 7800 rpm though.The tappet settings are .008 thou, on the inlet valves and .013 thou,on the exhaust valves,adjustment is with small round shims under the special new steel competition tappet buckets.
