HARDWARE FASTENERS www.TAPERFORMANCE.com TA Performance Products, Inc. 480-922-6807 Order and Tech Line 23 TA Performance offers quality head stud kits to replace stock head bolts on your Buick. Our head studs improve cylinder head sealing and ensure consistent torque values while saving the threads in the block from damage. In addition, studs help position the cylinder head and gasket during installation. Some kits include special undercut studs that reduce head gasket failure (see listings). Studs are made of heat treated 8740 chrome moly steel, hardened parallel-ground washers and heat treated nuts. Black oxided. Recommended for both street and competition. Please Note: Many of our stud kits are TA Exclusive items, made to our specification, resulting in hardware that fits and performs better than pre-packaged kits.

They are also good insurance if using nitrous on street/strip combinations. However, one thing to take into consideration is head studs can hamper the removal of the cylinder head when the engine is installed in the car. Brake boosters and air conditioning/heater boxes may obstruct the head from being able to be raised high enough to clear the studs. Studs or Bolts? Undercut Note: TA offers undercut head studs, doing so increases the clamping force applied to the cylinder head. By undercutting the shank, the stud is allowed to stretch when torqued to specification, thus creating a consistent clamping load under all hot and cold conditions. The fastener is constantly trying to return to its original state (like stretching a rubber band, the farther you stretch it, the harder it pulls back). Only the shorter bolts are under cut, the longer bolts already have a stretch factor, this way all of the head studs stretch at a similar rate. TA Performance is the only one offering this type of fastener for the older Buicks. This type of fastener is highly recommended and is used in all types of high tech automotive racing engines world wide. TA 1134NH
