Performer RPM Aluminum Cylinder Heads - Oval Port
Edelbrock 60455 Performer RPM 454-O Oval Port Aluminum Cylinder Head Features:
- These oval port heads will support over 540 hp with 9.5:1 compression when used as part of the Edelbrock Total Power Package.
- Unique oval intake port shape produces flow similar to rectangular ports, but the smaller port size provides excellent seat-of-the-pants performance and crisp throttle response.
- Semi-open chamber design maximizes efficiency with streetable compression ratios.
- Smaller-than-stock 11/32'' valve stems promote excellent flow and lighter valve weight.
Tech Tip: To gain more spark plug clearance, Edelbrock recommends using Champion RC Series plugs such as the RC12YC (P/N 192-49776). They are 0.230'' shorter than a conventional spark plug and have a 5/8'' hex for easier access.
