]Just be careful with the stated measurements, it does not give piston material, heat treat, bore material and finish. The “Racing” note could refer to Roger and his alloy barrels etc. That clearance is tighter than I would run a road engine on iron bores, and the taper is more. for into I attach a Scott piston drawing that shows much bigger clearances…
