EVIL ENERGY Cylinder Head Bolt Kit
Premium 210K PSI Strength | 42CrMo Alloy Steel | Complete Installation Set
Upgrade your Ford 289-302 Cylinder Head Bolt system with the EVIL ENERGY Cylinder Head Bolt Kit, engineered for durability, strength, and reliability in performance and daily driving builds.
- 210K PSI Dual Strength for Extreme Use: Each Cylinder Head Bolt is built with a 210,000 PSI tensile/yield strength, exceeding OEM's 180K PSI rating. This superior clamping force resists breakage and prevents leaks in high-stress setups—whether turbocharged, supercharged, racing, or heavy-duty Ford 289-302 engines.
- 42CrMo Alloy Steel Durability: 42CrMo alloy steel balances hardness, toughness, and heat resistance, outlasting standard bolts in Ford Windsor 4.7L/289, 5.0L/302 engines.
- Cost-Effective vs. Stud Kits: Compared with head stud systems, this Cylinder Head Bolt Kit offers excellent value. Perfect for OEM replacement or budget-friendly performance builds, while ensuring premium strength for Ford small-block 289-302 standard deck engines.
- Easy Installation for DIY/Repairs: One-piece design for direct thread-in to engine block, simplifying DIY/professional maintenance with fewer steps than studs.
- Complete Ready-to-Use Kit: Includes 10×71mm + 10×111mm Head bolts, 20 washers, grease, and manual—no extra parts needed for 1963–1969 Ford 289, 1968–2001 Ford 302 engines.
