Intake manifold studs

[vichang4]

One quick question just to be safe,

I am installing the intake manifold studs into the heads. What should I use to do this? Locktite Red? Blue? something else?
It probably doesn't make a difference but, this is on a 87 930, so the studs are fairly long ~ 6".

Wayne, this is one of the few things that I could not find in your excellent book.

I wouldn't put Loctite on them but that's just me.

Here I am agreeing with Chris again, but that is a good thing. If anything I would just put some anti-sieze on them.

No locktite? None of the studs backed out when I removed the intake manifold, so I assumed Porsche used some sort of thread lock on them? CE removed them, so I don't know what kind of effort it took to get them out.

Steel studs in aluminum often don't need the assistance of Loctite to become, shall we say, "resistant to change".
As a data point, Raceware head studs specifically state not to use Loctite on them.

I don't think you need any Loctite - it's not like you're going to be taking your manifold on and off many times in the future...
