Doesn't the lash reduce when the engine heats up and the valves get minutely longer?


That's the essence of the design. The spring still has about about 1mm clearance past max lift of the cam. The piston to valve clearance is 1.4mm. Were the valve to try and float, the valve slams to a stop and breaks the cast rocker arms rather than punching into the piston.
