Hi Leaf.
Is it the centre two pistons that are low in the block ?
It is common practice for high reving engines to have the centre two piston crowns machine so they do not hit the head at high revs.
Have your rods been white metalled ??
It is possible that the white metalling has been machined slightly off centre. so the centre to centre rod lengths need to be verified as well as the gudgeon pin to piston crown distance.
You can either take it all apart and do some accurate measurements if you are racing it.
Or make sure nothing is clashing and enjoy driving the car.
I am running an engine with 20 thou machined off the centre two pistons Its a 6500 rpm capable engine.
