ARP ARP2000 Head Studs SCE Vulcan Cut-Ring Head Gasket Kit 84mm Bore 1.0mm Supra A90 20+ 3.0L B58B30

ARP Head Stud Kit 12pt ARP2000 203-4705

Head studs hold your head and block together. As you make more power than your engine was designed to hold from the factory, the head and the block push apart from each other, stretching the factory bolts, and causing various failures. ARP Head Studs are stronger than the factory fasteners, and are designed to keep your race engine together under any circumstance.

Factory fasteners were not designed for performance use. The material chosen by the Original Engine Manufacturer for your engine's factory fasteners was chosen to meet the criteria of a normally driven consumer vehicle at the provided stock horsepower and rev limit. The material is not optimum for a high revving, high heat, high power, race car.

The factory fasteners were also not designed to be reused. Every time you torque a fastener, it stretches to perform the proper clamping force. If the fasteners stretch too far, they will not longer provide the required clamping force, and can lead to an engine failure. When you take your factory engine apart to build it into your race engine, discard your used factory main bolts and switch to a brand new set of ARP Head Studs to provide your engine with the proper clamping force required to keep all of your parts together in the harshest race environment.

We have seen heads lift and blow head gaskets, pressurize the cooling system, and worse. ARP Head Studs are a very inexpensive part that couldn't be more important to your engine build. Consider them a must.

SCE VULCAN CUT-RING Head Gasket CR330155

A hybrid design forged to harness the best sealing properties of two head gasket types:

Pliable, perforated metal-core composite gasket body eliminates coolant and oil leaks. No sealant needed!

Solid stainless cut-ring ‘bites’ into the cylinder head forming a positive barrier against combustion pressure leaks. No machining required!

Designed for use with high static compression or forced-induction engines which are prone to combustion pressure leaks when using typical composite or MLS head gaskets. Especially 4-bolt-per-cylinder patterns such as BMW, Subaru, Toyota and Chevrolet LS series.

Engine Sealing Capability Exceeds:

• 16:1 Static Compression Ratio
• 35 lbs. Supercharged or Turbocharged forced induction
• 250 Shot of Nitrous Oxide
