Hi Matt,

Yes, the shoulder that carries the oring dictates the installed height of the stud I have set the top of the shoulder .5mm below the surface of the block...figuring that every little bit more depth gives a small amount more engagement.

So far I am thinking that the 95ft/lb torque setting should be applied when torquing dry...if using thread lube, the torque setting should probably be more like 80ft/lb. Im interestedto hear what UK engine builders recommend from their own experience.

Cheers,

Phil.
