Not really - in that the block dimensions (the overall casting) takes it into account. If this were not true, then you'd have "side specific" rods or piston combinations.

The crankshaft offset (about 0.265") does influence the valve angles as well as exactly how the pistons are located in relation to the crank pin at certain rotation angles (rod angles - relative to the centerline of the rod are different at TDC).


Attached is a cross-section drawing I made that shows a bit of what I'm talking about - hopefully you read it (this is 59x through 8BA - is different for 32 - 42):

Enjoy!
