OptiTorque 10515 BBC Head Stud Kit for Dart/AFR/GM Performance Heads

The OptiTorque 10515 is a precision-engineered head stud kit designed specifically for big block Chevy (BBC) engines equipped with aftermarket cylinder heads from Dart, AFR (Air Flow Research), and GM Performance. This complete stud kit provides superior clamping force and reliability compared to traditional head bolts, making it ideal for high-performance and racing applications.

Key Features:

• Designed for big block Chevy engines with Dart, AFR, or GM Performance cylinder heads
• Superior clamping force ensures consistent head gasket seal under extreme conditions
• Heat-treated alloy steel construction for maximum strength and durability
• Thread-rolling process creates stronger threads than cut threads
• Includes hardened parallel washers and premium hex nuts for proper installation
• Prevents head lifting and gasket failure in boosted and high-compression applications

Head studs provide more accurate and consistent torque loading than head bolts because the fastener is not twisted during installation. This kit is essential for engines producing high cylinder pressures, whether from forced induction, nitrous oxide, or high compression ratios.
