69. STUDS – “HEAD” OR “BLOCK”
  Uppers are usually rusted. When factory “standard” – studs were installed in a block they  
    expanded the hole. When they are then removed, you usually need to go to a .003 to take up  
    the slack. If the stud has removed some aluminum material go directly to a .006. Neither require 
  tapping first. If the stud has actually pulled out, you must use a thread insert. Buy our kit and save  
   the bother of transporting engine to a machine shop. With a repair  thread you may use a standard  
    stud and locktite. See page 173-174 for much more info on studs and stud sizes. 
  We now offer standard studs but in most cases you need at least a .003.                     
   
  BLIND ENDED NUT: For installing and torquing engine studs (double nutting can damage threads).    C2001    2 oz. 
    Installation tool kit to help install studs – See page 333.
   PRO-SUPER DUTY HEAD STUDS: These studs (8700 heat treated steel) are 7/16" where they go into the block and taper to 3/8" giving  
    considerably more strength. The larger size at the block allows you to tap (use std GH3 tap) and directly install these studs without using an insert (even if a stock stud  
    has "pulled out"). The larger block diameter also makes it less likely a stud will ever "pull out" again. You can see the difference compared to an original stud. These are  
    suggested with ALL roller rockers and great insurance for a "stock" engine.

HEADNUTS – ORIGINAL STYLE: Used ONLY on Upper Head Studs  
    These have the original style built-in “collar”, (just a flat washer under a regular nut is not suggested).  
    Our head nuts are heat treated & have been tested to over 55 ft/lb., however, they should not be  
    reused after the engine is run & the nuts removed. Head nuts and rocker studs should only be torqued  
  32-34 ft/lb. For all Corvairs. 12 needed to do two (2) heads.

PERMATEX #2 – I Love this stuff! Since 2006, I’ve used form-a-gasket #2 non-hardening sealer on water and  
air-cooled engines with exceptional results. It is the only material I’ll use on gaskets, slip fit connections, threaded connections, etc. I also  
use it on the keyway of harmonic balancers so that oil cannot leak out, threaded studs that could leak water or oil. Yes, it is “old fashioned”  
– it has been in use since at least the 50’s (maybe longer). Will move with the installed gasket and stays soft & sticky. Try it – I think you’ll  
love it too. 3 oz. tube goes a long way.
