In cases where street-driven vehicles have items protruding into the engine compartment, such as master cylinders, it may be necessary to use head bolts to enable the removal of cylinder heads while the engine is still in the car. However, studs offer a more consistent and accurate torque loading, as well as easier engine assembly and proper alignment of the cylinder head and gasket. This is because, unlike bolts that are "twisted" while being torqued, studs are installed in a relaxed mode and only stretch on the vertical axis when torque is applied to the nut. For those looking for a high-quality head bolt kit, the ARP 134-3609 LS SBC Head Bolt Kit is an excellent option for such applications. It's important to note that an undercut shorter stud can have a similar rate to a longer standard shank stud, which provides a more even clamping force on the head. As the head gasket may compress over time, it's recommended to check with the gasket manufacturer for retorquing requirements. Sku: ARP134-3609
