There is a 4mm difference in the stroke between the EJ20 and EJ25 Derrick and you normally try and compensate with a change of rods and pistons to bring the piston deck height back to where it should be.
It sounds like your getting ahead of yourself if you have already got the bottom end together without working out what pistons you need ??
