- 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.
