HEAD (Crankcase) STUDS
DO NOT REMOVE UPPER OR LOWER STUDS UNLESS IT IS NECESSARY. It is not considered advisable to remove and replace all studs just so they are new. We normally
will not disturb a stud unless it “comes out by itself” or the threads are so bad that it must be removed. We also cannot tell you for sure which size stud to get. If a "stock"
one just "backs out" then a new standard might work fine or you might need to go to a .003 OR .006 (or possibly years ago someone already used a .006!). We just can't
tell ahead of time. The new stud needs to go in and "grab" or when you go to torque the head nuts the studs will just turn. We can tell you that if the stud removes most of
the threads in the block that you will need to install an insert.
NOTE: There is no real way to measure the .003 OR .006 threads. These were terms that GM used but it refers more to
the pitch and width of the threads than the actual overall diameter .

INSERTS
You have your choice of HELICOIL or TIME SERTS. If you've never used HELICOILS you may find the TIME SERTS easier. Also, the TIME SERT has a flared head and will NOT
"travel" into the open end stud holes like a HELICOIL may. With HELICOILS you need to use standard studs. With TIME SERTS you need to use .006 studs and may still not
get the full torque on the stud, but the stud still should NOT pull out.
LOCTITE: We also suggest BLUE LOCTITE for use on the inserts and on the stud threads. LOCTITE LOCKNUT listed above.
The .02 oz. is enough for about 2 inserts and studs and the .2 oz. should almost do all studs in a block.
STUD KITS for INSERTS: KIT gives you (1) .006 stud and (1) .02 loctite for use with TIME SERTS.
UPPER HEAD STUDS – C8660 4 oz. LOWER HEAD STUDS – C8661 4 oz.
"BOOT" DIPSTICK 1960-64 C95 2 oz.
1965-69 C96R 2 oz.
