ARP 2000 Porsche 356 912 head stud kit inc. lube. Uses stock head fasteners.

$339.15

Our Porsche 356 and 912 ARP head studs have been manufactured by ARP for us since 2002 utilizing their upgraded ARP 2000 material over the standard ARP 8740 or stainless steel studs sold by other companies. These are specifically designed to provide accurate torque and tension on the cylinder head through repeated heat cycles and are the perfect complement to our Nickies cylinders. We recommend torquing to 24-28 ft/lb using the supplied ARP lube; it is also recommended that you re-torque the cylinder heads after the engine has been broken in and heat cycled several times.

We also offer an ARP case thru-bolt as an optional upgrade that is an LN Engineering exclusive.

ARP hardware is a must on all performance Porsche engine builds; ARP head studs are proven and tested for a lifetime of reliability and performance and are required for use with Nickies cylinders. (ARP or equivalent upgraded head studs can be used where OE head studs are not compatible or recommended).

Description

The reason for offering replacement studs stems from the fact that our testing found that no available head stud was compatible with our Nickies™ or any aluminum cylinders for that matter, with exception of the 911 models equipped with aluminum cylinders from the factory. In most cases, the factory head studs are unable to perform satisfactorily under the increased expansion of an aluminum cylinder, in most cases leading to head leaks and fastener fatigue.

 

On 911 models, certain engines came fitted with Dilivar head studs, which were designed to match the expansion of the cylinders, but also suffered from hydrogen embrittlement, which is a condition that results from the accumulation of hydrogen gas in the atomic structure of the metal. This gas flows to the point of high stress (stress risers) and causes microscopic cracks. The hydrogen then flows to the “new” crack tip and causes it to crack further. In this way the crack moves across the part, because the crack-tip IS the stress riser. Finally the crack gets so large that the section is not large enough to support the load. Hydrogen embrittlement can take place without tensile stress. ARP® employs a baking process that purges hydrogen gas from the steel, eliminating this problem.

Important: Before ordering, always confirm that the part fits your specific type/model/engine.
