It is virtually impossible to say whether a blue printed engine has been modified or whether they just got a whole bunch of parts and matched them up. That's the problem. A blue printed engine is within spec as is the engine built from a big pile of slightly mismatching parts and is an engine straight off the production line.
Trying to stop anything like blue printing is ridiculously expensive. The only way to do it and be sure is for MNZ to own all the engines, seal them and dish them out. That's not going to happen.
Interpretation is not up to us and this result means blue printing is perfectly legal, as it should be.
But, the rules should not need interpretation. For instance saying "only OEM produced parts that are within the manufacturers spec (may be modified to conform)" would completely clear it up.
