Sorry, don't want to be an example good or bad.
I am not a builder, just an old hobbyist that has restored a few cars which all happen to be Porsches.
I ask questions so I can learn from others. But, in the end the decisions are mine and I own them.
However, I am guessing that Porsche's manufacturing tolerances are quite different than assembly tolerances. One is done in a controlled environment using precision tooling, and the other you try to control the variances. These engines are not swiss watches and have proven to be dependaple, reliable, and rugged over 50 years.
I did not expect anyone to put their reputation on the line.
I enjoy the different opinions and ideas.
I always enjoyed my fathers advice and sayings. But his strength and knowledge did not really include Porsche engine building based on application.
