When installing manifold studs, for the inlet and exhaust, would it be best to loctite them in?

If so, what loctite should I use?

What other bits and pieces should be treated to a dab of loctite on a rebuild?

Thanks,

You can loctite the intake studs, use anti-seize on the exhaust studs.

Red or green would do.

Use antiseize on the nuts when torquing to spec.

So anti sieze the exhaust manifold ones to stop them welding to the head I guess?

Ok cool. What about any of the head bolts, rod bolts, that sort of thing?

Thanks,

If you are using head studs, those go into the block dry. The upper threads get assembly lube or antiseize. Rod bolts get the same treatment. For main studs, again they go into the block dry with the cap end getting antiseize/lube.

Cool, thanks for clearing that up for me

So are head studs ever "tightened" into the block or are they simply threaded into place and tension holds them?

If they are are tightened, what method is usually used? Double nutting? Stud puller socket?
