Supertech valve guides are manufactured from high quality Manganese Bronze for sport compact and domestic applications. Our valve guides are designed to be used in combination with our low friction Black Nitride valves to provide the best solution for both performance and durability.
For exhaust applications in high powered engines that need a better thermal transfer coefficient, we offer copper alloy guides. Copper has about a 3x higher thermal transfer rate than manganese bronze, pulling heat out of the exhaust valve stem more effectively.
For any performance cylinder head rebuild — from street ports to full race heads. Guide installation and final honing should be performed by a qualified machine shop.
