摘要

Getting ahead in the engine building business today requires working on a wide variety of different types of cylinder heads, everything from small air-cooled engines and pushrod V8s to multi-valve heads and diesels. Most shops don't have the luxury of specializing in only one type of engine. Most shops have to work on almost any kind of engine that comes through the door. Late model passenger car engines with multi-valve cylinder heads and overhead cams can be time-consuming and challenging to work on because of the smaller valves and guides and the complexities of the head itself. There's almost no margin for error when machining valve seats and replacing guides. It's the same situation with performance work. The valve work you do has to be perfect for the head to hold up in a high heat, high RPM racing application.
