The Edelbrock #60549 Performer RPM Bare Rectangle Port cylinder heads are designed for Big-Block Chevy applications. The Edelbrock #60547 Performer RPM heads are perfect for street performance, daily drivers, street rods and muscle cars where seat-of-the-pants performance is needed. These cylinder heads deliver great throttle response and power from 1500 to 6500 rpm. They also feature the highest quality intake and exhaust valves and valve springs. For use on pre-pollution controlled vehicles only.

INSTALLATION NOTE:
• Bare heads will have valve guides & seats installed, but will require final sizing & a valve job to match the valves you will be using.
• Recommended spark plugs are Champion RC12YC or equivalent 14mm x 3/4" reach with flat gasket seat.
• All Performer and Performer RPM Big-Block Chevy heads: Spark plug is closer to center of bore, will interfere with high-dome pistons for open chamber heads.
• Use pistons designed for our heads. Match with Edelbrock head gasket sets.
• Designed for street/high-performance big-blocks operating from 2500-7000 rpm
• Specially designed ports for increased flow and velocity over standard big-block cylinder heads
• Highly-efficient 118cc open-style combustion chamber
• High-velocity 315cc long/300cc short intake ports
• Smaller-than-stock 11/32" valve stems promote excellent flow and lighter valve weight
