[Mg-t] more td head questions

Ok, but remember the MG "B" series engines are NF threads.
XPAG is metric 10 x 1.5 mm head stud.

In my experience, there is nothing wrong with original head studs with nuts
torqued to 50 ft-lbs for a cast iron head.
My TC race engine has an aluminum Lucas Laystall head and the nuts are
torqued to 42 Ft-lbs.
I doubt stronger head studs are necessary or even desireable, you might just
bust something else??

So far, I have never had a head gasket failure with either cast iron or
aluminum heads. I think there is something else wrong.
Good luck sorting it out. .

Check with Advanced Performance Technology, Riverside CA,  951-686-0260.
They carry 190,000 psi studs for the B series engine, and might have for
XPAG also.
