The engine industry is continually changing, and in order to be competitive, you must be up to date with the latest style machinery.

Intensive Cleaning Process

Our cleaning process is one of the most intensive in today’s industry. Once we receive our core cylinder heads, they are sent over to our Hot Tank which uses an aqueous solution to remove the grease and oil from the head. After that process is completed, the valves are sent over to our Glass Bead machine which is very aggressive in restoring the valves to give it a shiny new finish. The cylinder head is then placed in an Ultra Sonic machine which uses electricity along with water to help remove carbon from all ports and water jackets. The engine is then sent over to the machining department to begin restoring the cylinder head to new condition.



Latest & Most Advanced Machinery

ADV Cylinder Heads uses what is called a PCD (PolyCrystalline Diamond) to mill all aluminum cylinder heads and CBN (Cubic Boron Nitrate) for cast iron. PCD is a diamond stone which is the only material recommended to cut aluminum cylinder heads. The Rottler S7M is accompanied by a cutter with 2 separate diamond inserts. The Rottler VR7 refaces the valve to provide the perfect 45 degree angle to make sure the valve sits tight in the head. It also grinds the valve stem/Butt. In addition, the 3 angle valve grind will grind the valve seat to the perfect angle to ensure proper valve closure. Once the valves are ready, they are inserted in the cylinder head and checked using a vacuum valve seat tester. This machine will suck air from the intake to ensure the valve and valve seats have been machined properly. If the vacuum valve seat tester senses a leak from the valve, this means the valve or valve seat was not ground properly and the head will be re-ground to ensure proper valve closure. Once the head is complete, it will be sent over to the Trego Pneumatic Valve Spring Press. This is the finest spring press available in today’s market. This machine will assemble the valves and valve springs in the cylinder head. The head is now complete and ready for packaging.









Quality Control

ADV Cylinder Heads undergoes an extremely meticulous quality control process to ensure our cylinder heads are the highest standard. After our cylinder heads are cleaned, they are sent over to Sunnen Pressure tester where the cylinder heads will be inspected for any hairline cracks which are not visible to the naked eye. If the machine head is cracked, it will not continue to the next processes of remanufacturing. This is how we continually strive to provide the highest quality of cylinder heads and assure our customers that if has been tested and ready to install. Please be advised that we do not include camshaft seals on any of our heads.
