That may address any issues with the lip seal but it appears that some people are having issues with the retainer to block side seals and in some cases the retainer to block parting line.
All the hype about clocking the seal halves doesn’t hold any water as the engine plants never did this nor did they use any sealing compound. I don’t recall any epidemic of seal leaks back in the day either.
I think what is happening is people using worn out parts, improper installation techniques and/or sequences, maybe an occasional bad or wrong part and not being observant on the initial engine mock up and build.
