As far as I know the td42 non-turbo motors are all the same,
You may be getting mixed up with the tb42 and tb45?? as the tb45 has weaker rods and different pistons.

gu 4.2 diesels had lighter pistons in them than earlier gq 4.2.
it was to try and make the engines a bit quieter,they are a bit weaker though.
boost should be kept at about 12psi max.

Read this thread, it'll answer just about everything for ya.
Early td42's before changes had a silver rocker cover, after that they were/are black top.
