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.
