Performer RPM E-Tec 200
Performer RPM E-Tec 200 cylinder heads have all of the same great features as our E-Tec 170 heads, but feature a 200cc intake port and 80cc exhaust port for maximum flow. These heads outflow other aluminum heads of a similar design by 10% on the intake and 17% on the exhaust, making power up to 6500 rpm. The 64cc chambers produce 10.2:1 compression with flat-top pistons in 350-inch engines.

Technical Notes: Match with Edelbrock head gasket sets. 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. Recommended spark plugs 14mm x 3/4" reach with flat gasket seat (Champion RC12YC). To use stock rockers on small-block Chevy heads, .100" longer than stock pushrods are required. Edelbrock pushrods #9629 recommended. Use Head Bolt Kits for easy installation. S/B Chevy heads may not be used on engines with less than 4" bore (262, 265, 283, 305, 307 c.i.d.) except with cams having less than .450" valve lift. |
