No, each side drives both admission and exhaust valves on that side. The middle valves are driven by a cross shaft from one of the outer camshaft...
The pistons and valves are never in conflict, not like with an internal combustion engine where the valves open into the combustion chamber....
I'm struggling a bit with those figures and wonder how they were obtained. Stanier Pacific 6225 in 1955 and 1956, both on the rollers at Rugby and...
