Machine Work Performed:

1. Complete Disassembly & Cleaning
   We begin by carefully disassembling each cylinder head and performing a hot-tank cleaning to eliminate all carbon, sludge, and contaminants. Following the cleaning process, pressure testing is conducted to ensure the integrity of the casting and to detect any hidden cracks or flaws.

2. Valve Seat & Guide Service
   Our technicians replace valve seats as required, renewing valve guides to ensure proper seating and functionality. Additionally, all valve stem seals are replaced to prevent oil leaks and maintain proper oil control.

3. Precision Valve Job
   The valve job is performed with meticulous attention to detail, ensuring all valves and valve seats are ground to the precise angles required for optimal sealing and air flow. Each head is vacuum-tested to verify proper compression and overall sealing quality, ensuring efficient engine operation.

4. Surface Milling
   For a precise, smooth finish, each cylinder head is milled to the correct surface tolerances. We use PCD Milling (Polycrystalline Diamond) for aluminum heads, delivering a perfect finish that ensures optimal sealing. For cast-iron heads, we utilize CBN Milling (Cubic Boron Nitride), a high-precision method that guarantees durability and accuracy.

5. Assembly to AERA Specifications
   Every cylinder head is reassembled with the utmost attention to detail, using only high-quality components that meet or exceed AERA (Automotive Engine Rebuilders Association) specifications. This ensures that the head is restored to a condition that maximizes both reliability and performance.
