These high-performance aluminum cylinder heads have been designed to support over 540 HP in a big-block Chevrolet engine. Each oval port cylinder head uses a unique intake port design to increase flow numbers and performance. Performer cylinder heads have the same great features as the Performer RPM with the exception of the exhaust crossover passage for emissions applications. Part# ED60499 cylinder heads feature a smaller combustion chamber for a higher compression ratio.
