Exhaust manifolds are usually made from cast iron, and are big, bulky, and not designed for optimum flow. Headers are normally tube steel with a separate tube from each exhaust port to a common collector, this arrangement helps with flow, and scavenging, thus helping the engine to produce more power.

What gives you better performance headers or manifolds?
Headers. Because less or no exhaust back pressure.
What does a exhaust valve runnerlook like on a 350 Chevy engine?
They are the 4 large holes on the outside of the head where the headers or exhaust manifolds go.
On a Chevy 409 which valves are exhaust and which are intake?
The intake valves are bigger, and lead to the carburetor. the exhaust valves are smaller and lead to the manifolds or headers.
Will a 1967 289 fit into a 1964 falcon?
Yes. The only issue you may have is the exhaust manifolds. The Falcon has a little less clearance between the shock towers that the mustang. You may need to find some V8 falcon exhaust manifolds or purchase some aftermarket headers.
Where are the exhaust valves in the 350?
In the cylinder heads. The larger valves are the intakes. You'll notice that the passageway leads to the exhaust ports where the manifolds or headers attach.
What are headers on a car?
Headers are aftermarket replacements for the exaust manifolds. They are the parts bolted directly to the heads on the sides of the motor. They channel the exaust from each cylinder down to the exaust pipes.
What does it mean when a car needs new headers?
Headers (also known as exhaust manifolds) are the part that takes the spent exhaust gases from each individual cylinder of the engine, bring them together, and expel them from the vehicle (usually passing through one or more catalytic converters and one or more mufflers on the way). V-layout engines (V6, V8, etc) have two headers, whereas inline engines have just one. Usually, the term "headers" is only used for performance-enhancing aftermarket replacements for the factory exhaust manifolds. If a car needs new headers, that generally means that the existing manifolds have been damaged in some way. One common cause of this is rust.
What are Headers in cylinder head?
Headers are the pipes that connect to the exhaust heads. Commonly referred to as the manifolds headers are more often made of pipe that have been engineered to create equal back pressure to the engine at each exhaust port on the head, thereby allowing the engine to run more efficiently and evenly.
Did headers or exhaust manifolds come first?
Since they are really the same thing, there is no answer. An exhaust manifold is a header and vice/versa.The common cast iron 'exhaust manifolds' are quiet, last forever, and cheap to produce. The headers you refer to are more expensive, short-lived and can be very pricey. But the first guy who bolted a pipe on the exhaust post of his single cylinder motor to keep from getting burned by the exhaust created the first header. He also created the first exhaust manifold. Take your pick.
How do you put headers in a 350 engine?
hooker headers are a good header to use so unbolt the old manifolds u may have to cut the exhaust pipes and weld on a set of collectors that dont come with the headers then sometimes its better to put the car/truck on ramps and install them from under neath
What kind of headers can you install on your 95 Yukon that won't mess up for the smog check?
You might want to double check, but GM was using "Header-Like" exhaust manifolds from the factory. If that's the case, you won't get much improvement by putting on headers.
What would cause exhaust manifolds to get orangish red hot on 94 Toyota 4 runner?
Plugged converter possibly or other exhaust restriction. exhaust is very very hot, because of this, your exaust manifolds/headers are going to get very very hot, especially if you tend to run high RPMs. if everything else like throttle response is fine, i wouldn't worry
