Ditch any of the original MGA style (most have '22' on the top. Many of the
later better studs just have a centre pop in the tops.

2.) 50 lb-ft torque is correct for the iron head. Some aluminum
haed manufactures specify 40. Head studs of original quality will
tolerate 50-60 with some safety margin. Any stud that breaks at 40
is definitely sub-standard. If you have just installed a complete
new set of studs, one breaking at 40 makes the entire set
suspect. If you have no way of testing every individual stud, I
would be inclined to return the entire set to the supplier and demand
a refund, then buy the next set somewhere else.
