    Performer RPM Aluminum Cylinder Heads - Rectangle Port

    Performer RPM rectangular-port heads have specially designed intake and exhaust ports for increased flow and velocity over standard big-block heads. These heads feature a highly-efficient 118cc open-style combustion chamber for maximum performance. Engineered with high-velocity 315cc long and 300cc short intake runners, they are designed for street/high-performance big-block Chevys operating from 3500-7000 rpm. The stainless steel, hardened tip 2.19'' intake and 1.88'' exhaust valves have smaller-than-stock 11/32'' valve stems to promote excellent flow and lighter valve weight. The deck surface and water jackets were specially designed to work with all big-block Chevrolet engine blocks. Heads include top-quality ARP rocker studs, bronze guides and hardened, ductile iron valve seats.

    Note: The spark plug position and combustion chamber have been optimized for use with flat top or low dome pistons and will interfere with high compression, high dome pistons designed for stock Chevy open chamber heads. If a high compression domed piston is to be used, purchase a piston designed for use with the #350-6055 cylinder head.

    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.

    Edelbrock Performer RPM Oval Port Cylinder Heads
    These oval port heads will support over 540 hp with 9.5:1 compression when used as part of the Edelbrock Total Power Package. The 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. The semi-open chamber design maximizes efficiency with streetable compression ratios and the smaller-than-stock 11/32'' valve stems promote excellent flow and lighter valve weight.

    Edelbrock Performer RPM High Compression Oval Port Cylinder Heads
    These oval port heads are similar to the ones above with 100cc semi-open combustion chambers created by angle milling at a 1.5 degree angle to improve intake port alignment and create a smaller chamber without valve shrouding. They create an ideal street compression ratio of 9.2:1 when used with flat top pistons. Smaller-than-stock 11/32'' valve stems promote excellent flow and lighter valve weight.

    Edelbrock Performer RPM Rectangle Port Cylinder Heads
    These rectangle port heads are designed for street/high-performance big-blocks operating from 2500-7000 RPM. The specially designed ports offer increased flow and velocity over standard big-block heads. These heads feature highly-efficient 118cc open-style combustion chamber and high-velocity 315cc long/300cc short intake ports. Smaller-than-stock 11/32'' valve stems promote excellent flow and lighter valve weight.

    Marine Performer RPM Cylinder Heads
    The Marine Performer RPM heads feature heavy-duty, 1.89'' Inconel exhaust valves that provide added durability for marine applications. They are hard anodized to protect the aluminum in the harsh marine environment. These heads use smaller-than-stock 11/32'' valve stems to promote excellent flow and lighter valve weight. Match them with an Edelbrock Performer RPM manifold, Performer Series 750 cfm marine carb and Performer RPM cam for proven high-performance!
