I was looking into head studs for the KL series engine. I found a company that can make them but its big $$. I figured I'd post the info here if someone else wanted to look into it. It's stupid money really. Maybe if there was interest in 30+ sets the amount would come down. I honestly don't see 30 people or more jumping on the band wagon though. I also posted this info on probetak and the MX-3 board. Here is the last email I recieved-

I have investigated all options available to us to produce the special 11mm
head studs for the V-6 Mazda engine. Unfortunately none of the existing
fasteners that we sell will properly fit your application due to the 1.8"
thread length into the aluminum engine block. In order for us to provide
this stud, we would need special tooling specifically designed for the stud
that your engine requires. There would be a one-time charge for this tooling
of $800. It typically takes 3-4 weeks to obtain tooling after it is ordered.

Production costs on a single set of studs to fit your Mazda V-6 engine would
be $945 plus shipping and the tooling listed above. In quantities of (15)
sets or more sold to one person, and produced and shipped as one order, the
kit price would drop to $380/set plus shipping.

If you have any questions regarding this quote please contact us.

LOL, hopefully their tooling is a bit more sophisticated....

ARP rolls threads, they don't cut them. Fasteners with rolled threads are stronger.
