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. UPPER SUPER DUT Y STUD C10938 4 oz. ea. LOWER SUPER DUTY STUD C10939 4 oz. ea.

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. 3 oz. tube C715 2 oz. ENGINE DISCOUNT !see Blue pg. MK-2PICTURE #TORQUE ONLY 32-34 Ft.
