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.
