I went with this kit from AB: https://www.roverparts.com/engine/ga...ls/STC4082BKA/
It had everything I needed and then some. Included the head bolts. So far so good.

I've always used bolts.
Studs were basically designed for quick change situations, top-fuel drag racers or roundy-round day racers (where engine comes a part after each day of racing or after each run). Over time, running bolts into head causes wear or loss of threads...so...the stud was developed to rectify this issue. But, for normal, once or twice, head gasket job over the lifetime of a vehicle...not necessary.
Think about it... a nut has about four or five threads. A bolt has anywhere from ten to twelve that go down into head. Which one do you think is going to have the most holding power? Doesn't take any rocket scientists to figure out ten is better than five. Hell, even women know this. Applying torque to a fastener that has only four or five threads is a disaster waiting to happen, those threads are so stretched that they are surely compromised. Especially, in an application where the head gasket has to be compressed. Sure, you can use a nut in applications like rod caps and such, where they are basically holding the two pieces together, and not compressing material.
l've been a gas/diesel engine mechanic for 44 years, rebuilt more engines than l care to remember and work on diesels that are designed to go upward of 500 thousand miles...and what type of fastener do you think they use...a bolt...why...not because it's cheaper...but because it has more holding power...period.
A quality head gasket job is all about the prep work and installation. Cleaning bolt holes out, chasing threads, using new bolts, light lubracation of head bolt threads (not tons...light application!!!) and cleaning of block, head, checking for straighness, etc. And finally...following the torque sequence properly.
l'm not going to get in a debate about it...but will just finish by saying...studs are not necessary in this application...or in any way, shape or form better. If not worse. Studs have become an "internet sensation" because of a few folks that think..."if racers use them, they must be the best!".
EDIT...
To answer posters original question...l prefer Elring head gaskets.
