Sas....this worked out to be an excellent thread. Good on you and I am so happy to learn that you solved it. There are some great contributors on this forum and Diesel911 is one of them. Again the lesson is never assume anything.
Your OP was and I quote:
"Assuming the following:
- rebuilt, calibrated original set of injectors
- rebuilt head, including prechambers, valve guides, seals
- non-contaminated fuel
With no apparent fuel leaks, can worn delivery vales/sealing washers & rings be the cause of nailing? If so, how? "
So my answer held true because you did
NOT have properly calibrated injectors.
Properly calibrated injectors isolate the spray formation and pattern from pump issues (except for timing...of course) due to the pop pressure being the final arbiter in the sequence.
This is not about me being right or wrong (no ego tied up here! ) but I would like you to privately acknowledge that I did not mislead you
