Further to Tony's suggestion re bent crank or improper journal centre grind, try taking 1 assembled rod and piston (any one) and try it on each crank pin in sequence. If any discrepancy of piston crown height is found, the crank is at fault.
If no discrepancy follow Robert's advice and measure all pistons for pin to crown height.
If still no discrepancy, the BE white metal bore is suspect.
I must add I claim no expertise in engine building
