[TR] Removing Head Studs

[Bud Rolofson]

Roger,

Buy a stud remover like this one http://www.toolsource.com/stud-remover-32526-p-63350.html 
  (it works with a notched steel cam that grabs the stud and is turned  
with a 1/2 inch socket wrench) or rent or borrow one from one of the  
parts stores.   Those studs don't stand a chance when you put this  
tool to work.  Also its great for installing your studs to the block  
using with all the same torque settings (didn't take much--- 4 ft/lbs  
I believe ARP recommended).

I did the ARP studs when I rebuilt my head (1969 TR6 Circle B head  
that measures 3.461 inches) and am very happy with them although it  
getting at least one or two threads (the tapered threads) showing when  
the nuts were put on and torqued down was worrisome but it did  
happen.  You have to use their washers (0.118 inches) and that almost  
was too much stuff to fit on the stud and get the nut on with all  
threads holding to other threads securely  (the top couple threads are  
a bit tapered and are "guides" not holding threads).   The payen head  
gasket (AG900 for you TR6 folks) was 0.045 inches so it was real  
close.  I wouldn't leave one old stud in the head and the rest ARPs.    
Seems like inviting trouble (oil and water leaks) to me.  ARP is real  
specific about using their lube and their washers and torqueing them  
into the block correctly so that tells me the details are important.    
Maybe better to use stock studs all around if you can't get the last  
one out.
