Review DOUGS HEADERS Header

Doug's Headers D334-B is a high-performance stainless steel header designed for Ford 302 and 351 Cleveland engines. This header is a four-into-one design, which means that each cylinder exhaust port merges into a single collector before exiting through a high-performance collector and exhaust flange.

The header tubes are mandrel-bent for precise dimensions and even wall thickness, ensuring optimal exhaust flow. The collector and exhaust flange are also CNC-machined for perfect fitment and precision.

This header comes with 1 7/8-inch primary tubes, which are larger than the stock exhaust tubes. This increase in diameter allows for better exhaust flow and increased horsepower. The collector diameter is 3 inches, which provides ample room for the merge of the four exhaust gases.

The Doug's Headers D334-B header also features a removable stud gasket design. This means that the header gasket can be easily removed for maintenance or replacement, making it a more convenient option compared to headers with welded-in gaskets.

The header comes with a 5/16-20 thread exhaust flange, which is compatible with most aftermarket exhaust systems. The header is also designed to work with stock or aftermarket manifolds, making it a versatile option for various Ford Cleveland engine applications.
