[s-cars] Turbo to Exhaust manifold studs

[manuelsanchez at starpower.net]

Fellow S-heads,

One of the 4 turbo to exhaust manifold studs has worked its way out. I have a new replacement in hand but wanted to confirm with those wiser than me that the end of the stud that goes in first is the end that is closer to the unthreaded "shoulder". This untrheaded portion looks like that small section of worm thats a bit thicker than the rest of it.

Never having installed one of these I was wondering what the orientation should be and how far in the stud should thread into the exhaust manifold before I know its in far enough. It does not seem to bite into too many threads before I stop threading it in by hand...wondering if this is normal.

The copper nut also seems to only thread onto the stud for a short portion when threading by hand. I was also wondering if that is by design, so that when I put a wrench on it finally the nut will thread the stud further into the manifold.

Thanks.
