The ARP 235-4328 head stud kit is specifically engineered for Big Block Chevy engines equipped with Dart Pro1 cylinder heads featuring 20-degree valve angles. This precision-manufactured kit provides superior clamping force and reliability compared to conventional head bolts, making it ideal for high-performance and racing applications.

Key Features:

• 12-point head design for improved tool engagement and accurate torque application
• Custom-engineered specifically for Dart Pro1 20-degree cylinder heads
• Manufactured from premium 8740 chromoly steel with 200,000 PSI tensile strength
• Black oxide finish for corrosion resistance
