3.1 LH0 exhaust manifold bolts specs/part numbers?

Looking to replace the exhaust manifold gaskets on my 1992 Regal 3.1, thought I might as well put in new exhaust manifold bolts.

Did my homework but the information is unclear, are they bolts or are they studs? Are they M8x1.25x70mm bolts or M10? Does Dorman or similar aftermarket maker has a kit? Rockauto does not show anything unfortunately.

Take the fasteners out, match them up at any decent hardware store or Fastenall.

 

You'll want the same grade of fasteners, or a step up in strength/hardness.  NOT a step down in strength/hardness.

 

Reinstall at 80% of torque spec, using anti-seize on the threads and under the bolt heads.  The lubricant properties of the anti-seize will mean that 80% of torque spec still gets the bolts as tight, since you won't be fighting as much friction.
