Where can I get a 400ex head bolt stud kit?

[Narly R]

I have heard of a "Edvanced Stud Kit" for a 400ex, to fix the head bolts, but I cannot find one. Anyone know where I can get one at? Thank you.

Send your cylinder in and let them put the studs in.... that is, unless you like to replace head gaskets.... :bandit:
