FAQs
1. What is a Head Bolt, and why is it important?
A Head Bolt, also known as a Cylinder Head Bolt, secures the cylinder head to the engine block. It ensures the head gasket seals properly, preventing leaks of coolant, oil, and combustion gases. High-strength options like the EVIL ENERGY Head Bolt provide reliable performance under extreme pressure in SBC engines.
2. Is the EVIL ENERGY Head Bolt Kit compatible with Chevy Small Block engines?
Yes. The EVIL ENERGY Head Bolt Kit is designed for Chevy Small Block Gen I engines (265/283/302/350/400, 4.3L–6.6L, 1955–2000). It offers a direct fit, making it the ideal Chevy Head Bolt Kit for both OEM replacement and performance upgrades.
3. How strong are EVIL ENERGY Cylinder Head Bolts?
Each EVIL ENERGY Cylinder Head Bolt provides 210K PSI tensile and yield strength, surpassing typical 180K PSI OEM bolts. This extra strength resists stretching, breakage, and cylinder head leaks in turbocharged, supercharged, racing, and heavy-duty SBC Head Bolt applications.
4. When should I replace Head Bolts on my Chevy engine?
You should replace Head Bolts whenever you remove the cylinder head, change a head gasket, or notice signs of corrosion or stretching. Using a new EVIL ENERGY Head Bolt Kit ensures proper sealing and reliable clamping force, avoiding costly engine damage.
5. What material are EVIL ENERGY Head Bolts made from?
The EVIL ENERGY Head Bolt Kit is manufactured from 42CrMo alloy steel, a premium material that balances hardness, toughness, and heat resistance. This makes EVIL ENERGY Head Bolts more durable than standard steel fasteners, perfect for high-performance Chevy Small Block Head Bolt replacements.

Very happy with the look and the install. Takes a bit to figuring out the pieces you need. I wished they sold the stainless steel hose and black fitting in a kit. I hade to buy separately. Getting the parts to fit up wasn’t too bad. Figuring the right adapters was a bit tricky.

I installed it in a v8 swapped ford ranger!
I used some nylon spacers and riv nuts to attach this to my inner apron. As long as this doesn't leak when filled, I see no problems. This should do its job just fine. To be safe I used some teflon tape on the threads. I've used all evil energy fittings, lines, and hoses on this build. Mostly purchased from amazon, prime shipping is a game changer. So far I have not been let down; only impressed. Thanks EE!

This is insane I have bought many carburetors online before and it's always a hassle, lots of adjustments or a slew of unforeseen problems. Just as the other reviews state the product was delivered next day and everything matched perfectly. I installed it in about 20 minutes, primed it twice and on low idle it fired up on first pull. Literally unreal!
