Exhaust Header VS Manifold, which is the better choice?

The structural differences between exhaust headers and manifolds are the material and size. From the material, exhaust headers are made of lighter, thinner steel, while exhaust manifolds are made of thick iron. Exhaust headers are also longer than exhaust manifolds. When in use, exhaust manifolds create back pressure, which lowers performance. Because each cylinder of the engine is given its own tube, however, headers eliminate this problem; thus, allowing the gases to exit without the creation of back pressure. Therefore, exhaust headers are a BETTER choice than an exhaust manifold.

Replacing or upgrading your exhaust header is necessary for both engine performance and sound. Whether on or off the track, exhaust headers provide more horsepower and improved exhaust sound. FLASHARK offers many products to help you create your own custom engine headers. It's really easy and convenient to use: direct bolt-on, no modification needed.

K10 ls swap 4 speed

Bought these for an ls swap on a 1973 k10 4 speed they clear the clutch linkage and front drive shaft only problem was on passenger side they hit the frame on the second tube back from the front of the motor with a little heat and a hammer I flattened the side of that tube a 1/4 inch or less and made it work

Hello, we have taken a close look at your information and there are several factors you need to consider in order to determine if the exhaust headers for the 1964-1988 Chevrolet Chevrolet Pontiac Buick LS1/LS2/LS3/LS6 LS Swap Long Tube V8 engine will fit a 1973 K10 with a 4-speed transmission.

ENGINE COMPATIBILITY: The LS1/LS2/LS3/LS6 engines are modern V8 engines that were not available in the 1973 K10. A typical 1973 K10 will be equipped with a traditional small block or big block engine. Therefore, installing an LS engine may require modifications to engine installation and compatibility.

Chassis Compatibility: The exhaust headers you mentioned were designed for installation with LS1/LS2/LS3/LS6 engines. 1973 K10 chassis design and engine compartment configuration may differ from later models. This may require modifications or adjustments to the exhaust headers for proper installation.
