BIG VICTOR CHEVY PRO-PORT RAW
Intended for high output, large cubic inch big-block Chevrolet racing engines with 4.84" bore spacing, this new Pro-Port Raw head is an improvement on existing 18° heads with large oval ports such as the Big Chief and Big Duke. Hot Isostatic Pressing (HIP) process creates a super strong A-356 aluminum casting for superior durability, longer life between rebuilds, dimensional stability, and better machined finishes. It is the perfect compliment to our Big Victor manifolds, which have already become popular with the racing world due to the big power gains over other designs. The ports are cast extra thick to allow for professional porting with a custom CNC program and the chambers are compatible with most 18° Big Chief style pistons. Working in conjuction with Jesel, the valvetrain problems common to other designs have been solved by relocating 2 of the valve cover bolt bosses, requiring the use of Edelbrock valve cover #4259. Due to refinements in valvetrain geometry, special Jesel shaft rockers must be used with this head. Guides and seats are included but not installed. |
