1971 198 slant 6 manifolds

I'd see about an arp bolt if they make one the needed dimension.
I use their pontiac oil pan stud kits on the intake/exhaust head studs. They have round ends....so never hurt the threads or break then off...stronger than the head. Fine thread too, get them nice 'n cinched.

Depending on how far you want to take this, how about grade 8 fasteners.

That's all I will use on them.

I've used #316 stainless in my last couple of manifold stacks.

Stainless is nice, but it's not as hard as grade 8.

Like regular hardware there are different grades of stainless.
With what torque is called for grade 8 works but it's overkill

You mean like a Dana 60? That's a good thing, right? lol
