is for good reason that virtually every top professional engine
builder relies on ARP Pro Series head studs for their all-out
competition powerplants. Simply stated, there's not a
better stud setup on the market today. For openers, ARP uses
a premium grade 8740 alloy that is rated far superior to “aircraft”
quality. Then, each stud is placed vertically in special racks
and precisely heat-treated to 200,000 psi. This procedure ensures
complete heat penetration and the results are far superior to
those lesser quality studs from other manufacturers who just
dump pieces in a basket and hope for the best.

made of proprietary ARP 2000 material in Santa Paula, CA
ARP studs are rated at 220,000 psi tensile strength, and provide
the clamping force required to keep cylinder heads from lifting
due to higher combustion pressures. The studs are manufactured
in ARP's Santa Paula, CA plant from proprietary ARP 2000 material,
with threads rolled after heat-treat to provide optimum fatigue
strength. They are centerless ground to assure perfect concentricity.
The ends of the studs are broached to facilitate easy installation.
This feature also enables the cylinder head to be removed in
tight quarters. Also included in each kit are heat-treated,
chrome-moly steel 12-point nuts and parallel-ground washers.
They are black oxide finished for extra durability.
