- 1967-1991 Small Block Chrysler 318-360ci
- Fully CNC Ported
- Port Volume: 225cc/77cc
- 58cc Combustion Chambers
- Bare, Sold Individually
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.

Since founder Vic Edelbrock Sr. began building performance intake manifolds in 1938, Edelbrock has grown into one of the most trusted names in American high-performance parts, from carburetors and intake manifolds to cylinder heads, crate engines, and EFI systems. JEGS has spent decades supplying Edelbrock components to racers, engine builders, and street enthusiasts, backing this extensive lineup with in-house technical support, fast shipping, and a Price Match Guarantee so you can choose proven Edelbrock parts with confidence.
Edelbrock has redesigned the Small Block Chrysler cylinder head for bracket racers and serious street enthusiasts. This 318-360ci Chrysler LA engine cylinder head features 100% CNC-ported 58cc combustion chamber, intake and exhaust ports. The first design enhancement is with 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. This head also uses a 5.56" overall length valve (+0.600" from stock) and raised rocker cover permit larger port cross-sections than in the stock head.
