Description:
Edelbrock Performer RPM 454-O high-compression cylinder heads offer smaller ports for bigger performance. Designed for big block Chevy's with oval ports, these cylinder heads feature unique oval intake ports that flow similar to rectangular ports but the smaller size provides excellent seat-of-the-pants performance plus crisp throttle response! And, the 100cc chamber volume is ideal for your high-compression application. Both the intake and exhaust ports of these Performer RPM heads have been profiled for improved air flow and they have smaller-than-stock valve stems for less weight and excellent flow. More flow, more power, and more performance for your big block application comes with a set of Edelbrock Performer RPM 454-O high-compression cylinder heads.
