[s-cars] RS2 Manifold Head Studs - 10.9 Hardness

[Djdawson2 at aol.com]

Sean,
I would recommend taking the stock length studs and cutting them down to the 
correct size.  I've got a small drawer full of RS2 exhaust studs, and found I 
don't like them because they seem to be too short.  After install, I noticed 
that with the nut tightened down over the expansion washer, the nut doesn't 
travel far enough down the stud to actually engage the locking ring on the nut.  
The result is an eventual loosening of the nut... and likely loss of both it 
and the washer before you notice it.

If you elect to shorten the stock length studs, test fit your manifold first. 
 You'll find that only 4 of them actually have to be shortened to fit.  IMO, 
this is a better way to go than the RS2 length studs.
HTH.
