Thanks for the replies Wes and Tabetha,

I did the last repair today and installed the last stud to 55ft/lb. I have taken some pics on the phone which are a bit average but show the thread penetration, hopefully someone can confirm if it looks consistent with most.

Part of the issue with threads pulling was with using ARP thread lube(recommended by the supplier). I have now discovered that with ARP thread lube, 95ft/lb is equivalent to 125ft/lb with engine oil as thread lube...or if using ARP thread lube, no more than 77ft/lb should be used. I guess we live and learn.

Here are some pics...
