Cylinder head restoration
Every Head We Service Goes Through Our Pressure Testing — and Here's Why.
A cylinder head may look fine on the outside, but hidden cracks or internal leaks can cause serious engine problems down the road. That’s why pressure testing is a vital part of every head we service.
Pressure testing allows us to check for internal flaws that can’t be seen with the naked eye. These flaws—like cracks between coolant passages or combustion chambers—can lead to overheating, loss of compression, coolant loss, or even complete engine failure if left undetected.
By simulating the engine’s operating conditions with air and water pressure, we can verify that the head is completely sealed and structurally sound before any further machine work or installation takes place. It’s a crucial step to ensure your engine will run reliably and efficiently after reassembly.
As we all know the devil is in the details. Pressure testing gives you peace of mind knowing your cylinder head is free of hidden defects and ready to perform.
Complete Cylinder Head Service – Built for Performance and Reliability
When it comes to engine performance and longevity, the condition of your cylinder head makes all the difference. At Intense Precision, we provide thorough, precision-based cylinder head services that help prevent future issues and ensure your engine runs at its absolute best.
Here’s what we inspect and service—and why it matters:
✔ Valve Guides
Valve guides keep the valves moving straight and true. Worn guides can cause oil burning, valve misalignment, and power loss. We carefully inspect and replace them as needed to ensure smooth valve movement and a tight seal.
✔ Valve Seats
Every time a valve closes, it seals against the valve seat. If these seats are worn or not properly shaped, your engine can lose compression and run unevenly. We resurface valve seats to restore perfect sealing and improve airflow and combustion.
✔ Valve Spring Pressures & Install Heights
Valve springs must be set to the correct pressure and height to keep valves operating in sync with the camshaft. Incorrect spring pressure can lead to valve float or even engine damage at higher RPMs. We test and adjust each spring to factory or performance specs.
✔ Valve Tip Heights
Proper valve tip height ensures the valvetrain geometry is correct, which affects how the camshaft interacts with the valves. Uneven tip heights can lead to poor valve lift, noisy operation, and premature wear. We measure and correct valve tip heights for smooth, balanced operation.
✔ Cylinder Head Deck Surface
A flat deck surface is essential for sealing the head gasket and preventing coolant or compression leaks. We Resurface the cylinder head surface to restore a flat, clean seal with the engine block.
We treat every cylinder head like it’s going into our own engine. Whether you’re rebuilding, upgrading, or just making sure everything’s right, we deliver quality you can count on—every time.
Final Cylinder Head Assembly – The Last Step Before It’s Ready to Perform
Once all machine work is completed—such as pressure testing, resurfacing, valve seat cutting, and component inspections—the final step is carefully reassembling the cylinder head with precision and attention to detail.
A key part of this process is installing new valve stem seals. These seals play a critical role in controlling oil flow around the valves, preventing oil from leaking into the combustion chamber. Worn or old seals can lead to excessive oil consumption, smoking, and reduced engine performance. That’s why we always replace them with high-quality, brand-new seals during reassembly.
Next, we install the valves, springs, retainers, and locks—ensuring everything is set to the correct specifications. Every component is cleaned, inspected, and reassembled to meet or exceed OEM standards.
This final assembly process ensures your cylinder head is fully rebuilt, properly sealed, and ready for installation—giving your engine the performance, reliability, and longevity it deserves.
We don’t just rebuild cylinder heads—we restore them to their full potential.
