"Block relief" - L.M. Williams book
#20
Does the design of the Ricardo head not already optimise gas flow? I thought that's what they were good at...

"Harry Ricardo's contribution was to understand the combustion process and develop a cylinder head that retained the simplicity and the low cost of the side valve layout, but which rethought the shape of the combustion chamber to provide both the greater compression required for power, and the improved gas mixing that he realised was essential for stable combustion and the avoidance of damaging detonation. This he achieved with an asymmetric profile to the combustion chamber which used a squish effect to induce turbulence in the gases above the rising piston, compressing them into the chamber to one side, where they were ignited by the spark plug."

It's your call Jon. For me though the sentence which stands out in this thread is:
I've been resisting putting a new Ricardo on this engine as the engine is old and untested...
I have no hesitation in saying if you want to soup your motor up, first make sure you have a sound motor.
