Product Details

The Edelbrock 60549 Performer RPM bare cylinder head is engineered for high-performance Big-Block Chevy applications with rectangular port design. Manufactured from A356 aluminum and made in the USA, this cylinder head is ideal for street performance vehicles, daily drivers, street rods, and muscle cars where responsive power delivery is essential.

Performance Characteristics:

Delivers great throttle response and power from 1500 to 6500 rpm, making it perfect for street and high-performance applications operating between 2500-7000 rpm. These cylinder heads offer out-of-the-box bolt-on performance with no additional porting required.

Technical Specifications:

  • Combustion chamber volume: 118cc
  • Intake runner volume: 315cc
  • Exhaust runner volume: 110cc
  • Intake valve diameter: 2.19 inches
  • Exhaust valve diameter: 1.88 inches
  • Valve stem diameter: 11/32 inch
  • Manganese bronze valve guides
  • Deck thickness: 9/16 inch
  • Valve spring maximum lift: 0.700 inch
  • Rocker stud: 7/16 inch
  • Pushrod diameter: 3/8 inch
  • Valve angle: 26 degrees
  • Spark plug fitment: 14mm x 3/4 inch reach, gasket seat

Important Installation Notes:

Bare heads will have valve guides and seats installed, but will require final sizing and a valve job to match the valves you will be using. Spark plug is closer to center of bore and will interfere with high-dome pistons—use pistons designed for these heads. Match with Edelbrock head gasket sets.

Emissions Notice:

For use on pre-pollution controlled vehicles only.

Sold individually. Compatible with Big-Block Chevy 396, 402, 427, and 454 cubic inch engines with rectangular port intake manifolds.

Very easy site to navigate. Will do business with you guys again.

I looked every where for the valve keeper I needed, Amazon didn't even have it and eBay wanted way to much plus wanted me to pay more than the part for shipping. I'm glad I found it here

There is no estimated shipping other then that it was a good experience.

Been good so far this part is super hard to find but if in high demand

Love your site. Easy to find exactly what I was looking for.

fast and easy with fantastic prices compared to others
