Alta Cylinder Heads
It is good news for Austin Seven enthusiasts that the Alta aluminium cylinder head, which was in such demand before the war, is to be put on the market again. These heads produce increased power and smoother running, having carefully-formed combustion chambers in which the sparking plug is inclined above the exhaust valve in the best modern tradition. The head fits any Austin Seven, using a standard gasket, and increases the compression-ratio from 5 to 1 to 6.2 to 1. Before the war the claim was made that the Alta head was well-suited to No. 1 petrol, so it should be just the thing for use with “Pool.” There is, naturally, some reduction in engine weight by using one of these heads. The price is £5 10s. and the manufacturers are the Alta Car and Engineering Co., Ltd., Fullers Way, Kingston By-Pass, Surbiton, Surrey.
