I've not heard any complaints of Porschetek but they're half way to Bolton from you and I have dealt with Hartech many years ago, I would expect that Porschetek are more than capable but to do this job it is a bottom end strip and rebuild so best to get quotes from both after telling them both what you have been told is wrong.
Hartech have done some development on improving the oil jets and a few other things but read about it on their buyers guide.
