Will JB Weld work on cast iron exhaust manifold?
JB Weld ExtremeHeat is perfect for making repairs on all manner of high-heat parts, including exhaust manifolds, mufflers, catalytic converters, exhaust pipes, engine blocks, fireplaces, smokers/fireboxes, and many more crack-prone items.
When did cast iron exhaust manifolds come out?
The castings varied over the years, but the castings from the late 1960’s to early 1970’s generally offer the lowest restriction and best flow of the possible choices (the obvious exception being the Max Wedge/Ramcharger 413/426 1962-64 items, which are now priceless).
Do you need headers or cast iron exhaust manifolds?
While headers may offer more performance, nothing fits a specific car like the stock cast iron exhaust manifolds, and when the car is restored or original, they are necessary. The problem with cast iron, especially exhaust manifolds, is that it rusts.
What kind of exhaust manifold do you use?
Exhaust manifolds can either be a cast iron, factory-type manifold or a tube steel header typically used in performance applications, though they are becoming very common in OEM applications. There are a variety of reasons for coating an exhaust manifold header.
Can you put graphite spray on exhaust manifold?
Mark Simpson demonstrates how to freshen up the look of the cast iron parts with an exhaust manifold coating, dry graphite spray, that looks good and is easy to touch up. Click here to cancel reply. Very cool idea. But, when it dries, I take it that it will not wipe off. I mean, it is like paint and is a finished product ?

What causes rust on cast iron exhaust manifold?
The constant hot-cold cycling creates a lot of moisture, which causes rust on the cast iron, wrecking havoc on their appearance. The typical restoration practice involves cleaning and painting. Painting exhaust manifolds has its own set of problems.
Where does the 289 high performance exhaust manifold come from?
These manifolds were cast at the Cleveland foundry based on the circle “C” logo. The 289 High Performance exhaust manifold looks like an iron shorty header. It also resembles the 351W exhaust manifold. This is a C3OE casting number manifold that may have been cast by an outside supplier. There are no foundry markings on this manifold.
What’s the best way to restore an exhaust manifold?
The typical restoration practice involves cleaning and painting. Painting exhaust manifolds has its own set of problems. If the manifolds are not perfectly clean, the paint won’t stick and flakes off. Even if they are sandblasted and ultra-clean, high-temp paints eventually burn off, leaving a patchy, unnatural looking manifold.
