Designed for 396-502 c.i.d. big block Chevy engines, these Edelbrock cylinder heads include heavy-duty exhaust valves that provide the added durability needed for marine applications, and have one-piece, stainless steel 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. They're cast from A356 aluminum and heat-treated to T6 specs. Their oval-port heads have 110cc chambers and their rectangular port heads have 118cc chambers. Both the oval and rectangular port heads are hard-anodized to protect the aluminum in the harsh marine environments.
