Complete Cylinder Head Services

Cylinder Head Inspection & Diagnostics

We perform full visual and dimensional inspections to identify cracks, warping, valve issues, guide wear, or surface imperfections. Accurate diagnostics help us determine the best repair strategy before machining begins.

Hot Tank Cleaning & Media Blasting

Cylinder heads are deep-cleaned to remove carbon, oil, coolant residue, and debris. Clean surfaces allow for accurate testing and precision machining.

Pressure Testing & Crack Detection

Our pressure testing process checks for internal and external cracks that can cause coolant loss, overheating, or compression issues. Every head is tested before and after machining for reliability.

Resurfacing & Deck Milling

We resurface cylinder heads to achieve a perfectly flat sealing surface, ensuring proper head gasket performance and long-term durability. This helps prevent overheating, leaks, and compression loss.

Valve Jobs (3-Angle & 5-Angle)

Precision valve machining improves airflow, sealing, performance, and fuel efficiency. We restore proper valve seating for smooth engine operation and optimal compression.

Valve Guide Replacement & Reaming

Worn guides affect airflow and cause oil consumption. We replace and size guides to OEM specifications for proper valve alignment and sealing.

Valve Seat Cutting & Installation

We machine and install new valve seats for damaged or high-performance applications, ensuring correct geometry and sealing.

Camshaft Bore Repairs & Machining

We check and correct camshaft bore alignment to reduce friction, improve timing accuracy, and restore reliable operation.

Cylinder Head Porting (Optional)

For performance enthusiasts, we offer porting to improve airflow, horsepower, and throttle response. Ideal for custom and race builds.
