Cylinder Head Rebuilding Process

1. Initial Inspection: As a unit comes to our shop, we will give it an initial inspection to determine if there are any reasons the head should not proceed to the rebuilding process. This inspection can quickly catch problems such as cracks, casting damage, and other situations that would halt the rebuilding procedure for that casting.
2. Teardown: Teardown is also important to the initial inspection process as the cylinder head is disassembled because you can determine other areas of potential damage to the casting. The parts and cylinder head are separated and go through different cleaning processes.
3. Cleaning Process: We use several different processes to clean cylinder heads.

• Aluminum Heads: Aluminum heads are either baked at a lower temperature or put into a high-pressure wash. They are also glass-beaded to give them a brilliant finish.

4. Head Inspection: After cleaning heads, they are then pressure tested or magnaflux to determine any cracks. All bolt holes and valve guides, in addition to the valve seat and other parts of the head, are inspected for damage such as broken bolts, broken taps, cracked guides, and other impairments. Straightness and cam bore wear is also checked.
5. Machining: All cylinder heads have guides installed to meet OE conditions. They are resurfaced to far exceed factory specifications on surface finish. Three angle valve job is performed to achieve a valve seat runout of less than .001. Valves are ground to make a perfect seal between the valve and valve seat.
6. Assembly: All heads have new OE-style valve guide seals installed. Springs are tested to ensure proper seat pressures. Valve seat sealing is checked with a vacuum to ensure an airtight fit between the valve and the valve seat. Lifters are bled and rebuilt to accomplish zero lashes after the startup of the engine. Cams are polished and clearances are checked twice to meet OE oil clearances.
7. Final Inspection: Heads are visually inspected. The surface finish, lash, bolt holes, and all other areas are inspected to ensure a quality cylinder head.
