Performer RPM 454-R Marine Rectangular Port, 118cc, pair of heads with valves only
Designed for 396-502 cid big block Chevy engines, these heads include
heavy-duty, 1.89" Inconel exhaust valves that provide the added durability
needed for marine applications and have one-piece stainless steel 2.25" intake
valves with hardened tips and swirl-polished heads. The high-velocity flow
capabilities of Edelbrock Performer RPM cylinder heads provide increased torque
across a wide rpm range that's ideal for marine use. Cast from A356 aluminum and
heat-treated to T6 specifications. The oval-port heads have 110cc chambers and
the rectangular port heads have 118cc chambers. Both the oval and rectangular
port heads are hard anodized to protect the aluminum in the harsh marine
environment. Edelbrock Big Block Chevy marine heads are sold with seals and
valves only for a variety of combinations. Match with a proven Harden Marine Cam
Kit for the ultimate in performance and value.
