Should I replace the exhaust manifold?
So the best advice for exhaust work: Replace it all. Of course, the meaning of “all” varies with the age and complexity of the car. On a vintage car with no catalytic converter, there’s usually a cast-iron exhaust manifold that lasts the life of the car. There is a manifold for each cylinder head.

What is a burned gasket?

Does cheapo gasket fit?
The cheapo gasket looks like it doesn't actually fit. If a gasket isn't clamped correctly, IE hanging off the side, of the application it is much more prone to blowing out. No matter what you are using the gasket on. I've seen fitment problems like that on aftermarket headers, but not factory manifolds. I've gotten some of those Mr.Gasket gaskets with a pair of blackjack headers. The left side fit perfectly but the right not at all. I immediately thought ill-fitting headers, but it turned out to be the gasket for some reason. A Fel-Pro metalized gasket fit much better.#N#The orange stuff is "High Temp Copper RTV" silicone sealer. It appears the mechanic was using it to compensate for a mismatch problem between the gasket and head. Seems unusual to have to do such a thing on stock looking parts. The Hi-Temp RTV is very much a viable solution though. Drag racers discovered years ago that you could use the stuff as a complete substitute for exhaust gaskets, which saved them a dollar or two on engines subject to regular teardown.#N#I've used it myself in oddball situations and have been surprised how well it held up in the long term. I don't know of another acceptable substitute though, including your hi-tack stuff. Manifolds can get hot enough to light a cigarette off of, very few sealants out there can withstand that sort of heat very long.#N#I advise getting a good pair of gaskets (NOT Mr.Gasket-Felpro is OK). When you get everything loose use the gasket to check your cylinder head ports. Don't just assume everything is OK and a simple gasket replacement will fix it, that's obviously already happened. Take your time and see if you can spot where gasket coverage is too "thin" that will make it prone to blowing out. Also check it up against the manifold too. If possible, checking just the manifold on the head without the gasket might reveal something. I suspect somewhere along the line something will catch your eye as not looking quite right. Then we get to figure out how, why, and what to do about it.#N#I have once seen a head that someone ported too enthusiastically that no gasket in the store would have sealed. Big rust pits in the sealing surface of a manifold, hidden cracks, etc. You never know. Hopefully it's something simple.
What gaskets do 2 strokes use?

Why is exhaust manifold gasket important?

How long does an exhaust manifold gasket last?
Generally, exhaust manifold gaskets are hardy items, often lasting well over 100,000 miles. A lack of engine maintenance and carbon buildup, however, can cause hot spots in the combustion chambers and exhaust ports. This can cause a gasket to catch fire or expand outward. This is a good reminder to use fuel system cleaners to remove carbon buildup.
