Valve Springs. We understand that valve springs are now being made of the improved pressure and size of wire and taper form and of Woodhead's steel, and hardened at our Works. Please understand it is really urgent that we should fit springs that will not let the valves leave their seats until the engine arrives at 2500 revs. R.{Sir Henry Royce} 258X | ||
