Victor Series Cylinder Head
These cylinder heads are for use on 1967-1991, 318-360 c.i.d. Chrysler LA engines. They feature fully CNC ported 58cc combustion chambers and have an intake port volume of 225cc. These cylinder heads are an in-line valve design incorporating a 16° valve angle (stock is 18°) for improved air flow and increased power levels over heavily ported stock versions. They also feature the Chrysler W5 bolt pattern and have raised exhaust ports. The intake port has also been raised approximately 3/4" and the flange has also been extended to accommodate a stock (race) intake manifold such as the Super Victor 350-2815. Finally, a 5.56" overall length valve (+0.600" from stock) and raised rocker cover permit larger port cross-sections than in the stock head. End-seal spacers are provided.

WARNING: Motor vehicles contain fuel, oils and fluids, battery posts, terminals and related accessories which contain lead and lead compounds and other chemicals known to the State of California to cause cancer, birth defects and other reproductive harm. These chemicals are found in vehicles, vehicle parts and accessories, both new and as replacements. When being serviced, these vehicles generate used oil, waste fluids, grease, fumes and particulates, all known to the State of California to cause cancer, birth defects, and reproductive harm.
Tools:
WARNING: Some dust created by power sanding, sawing, grinding, drilling, and other construction activities contains chemicals known to the State of California to cause cancer and birth defects or other reproductive harm. Some examples of these chemicals are: lead from lead-based paints, crystalline silica from bricks and cement and other masonry products, and arsenic and chromium from chemically treated lumber. Your risk from exposure to these chemicals varies, depending on how often you do this type of work. To reduce your exposure, work in a well-ventilated area and with approved safety equipment, such as dust masks that are specially designed to filter out microscopic particles.
