Very well constructed product. Fits the AMC 304 currently in my CJ-7, as well as the AMC 401 I'm building to replace the 304 when it tires. I like the bottom bracket exit which makes the car look more stock. Plugs that bolt to the manifold base plates are included, allowing for the construction and attachment of custom exhaust systems. These headers are sold uncoated but are painted with standard quality paint to prevent rusting during shipping and storage. High temperatures can quickly burn off this coating, so stripping is required before reapplying a high temperature paint or coating. You can't beat the price, especially considering the free shipping.
