Bolt Kits, Studs & Fasteners
Head Studs vs. Bolts…
A Technical Discussion
ARP’s factory Tech Representatives are often asked which is
better, cylinder head studs or bolts. The answer, invariably, depends
on the installation. On many street-driven vehicles, where master
cylinders and other items protrude into the engine compartment, it’s
probably necessary to use head bolts so that the cylinder head can
be removed with the engine in the car.
For most applications, however, studs are recommended. And for
good reason. Using studs will make it much easier to assemble an
engine (especially a racing power plant which must be serviced frequently
and quickly!) with the cylinder head and gasket assured of
proper alignment.

Rocker Arm Stud Kits
If you have ever installed a rocker stud into a
cylinder head and watched it wobble as it screwed in
- you knew from the beginning that the rocker geometry
was going to be inconsistent all over the place.
ARP rocker studs are concentric within .005 T.I.R.
thread pitch to thread pitch. they run-in straight and
true. Lengths are exact - designed to provide positive
seating every time. An extra-large radius base offers
greater resistance to flex.
High Performance Series
Made of 8740 chrome moly forgings and heattreated
to 180,000 psi. Excellent for E.T. Bracket
Racing, limited rule oval track competition and street
use. Tip ground flush for optimum adjuster seating.
Valve Cover Bolt Kits
Studs also provide more accurate and consistent torque
loading. Here’s why. When you use bolts to secure the head,
the fastener is actually being “twisted” while it’s being
torqued to the proper reading. Accordingly, the bolt is reacting
to two different forces simultaneously. A stud should be
installed in a “relaxed” mode - never crank it in tightly using
a jammed nut.
If everything is right, the stud should be installed finger
tight. Then, when applying torque to the nut, the stud will
stretch only on the vertical axis. Remember, an undercut
shorter stud will have a rate similar to a longer, standard
shank stud. This provides a more even clamping force on
the head. Because the head gasket will compress upon initial
torquing, make sure studs and bolt are re-torqued after
the engine has been run.
