Q1: What is the function of a Cylinder Head Bolt?
A Cylinder Head Bolt secures the cylinder head to the engine block, maintaining proper sealing under high combustion pressure. Using high-strength Head Bolts prevents leaks, warping, and engine damage—especially in performance or heavy-duty applications.
Q2: Why should I choose the EVIL ENERGY Head Bolt Kit over OEM bolts?
The EVIL ENERGY Head Bolt Kit offers 210K PSI tensile/yield strength, which exceeds OEM’s 180K PSI rating. This makes the EVIL ENERGY Head Bolt more resistant to breakage and leaks in turbocharged, supercharged, racing, or heavy-duty Ford 289-302 engines.
Q3: Which vehicles are compatible with the EVIL ENERGY Cylinder Head Bolt Kit?
The EVIL ENERGY Cylinder Head Bolt Kit fits Ford Windsor small block 289 (4.7L) and 302 (5.0L) engines, covering models from 1963–1969 (289) and 1968–2001 (302).
Q4: Is the EVIL ENERGY Head Bolt Kit easy to install?
Yes. Unlike stud systems, the EVIL ENERGY Head Bolt design allows direct thread-in to the engine block, reducing installation steps. It’s beginner-friendly for DIY users and efficient for professional mechanics.
Q5: Can EVIL ENERGY Head Bolts handle high-performance engines?
Absolutely. With 210K PSI tensile/yield strength, the EVIL ENERGY Cylinder Head Bolt provides superior clamping force and durability, making it ideal for boosted setups, track use, or long-term reliability in heavy-duty Ford engines.
