Yes Jim, same issue, I knew I had read about this in the past but could not find the link, TPS are still currently supplying cambelt kits without this new modified stud being incorporated in the kit, or any explanation as to why they have changed the stud??

In my case I had the engine rebuilder install a helicoil in the head with threadlock, and have told customer I wont be doing next cambelt change, someone else can have that experience
