While I was mocking up the exhaust manifold for customization/lengthening I realized that I had to lift the motor 15cm every time I removed and installed the manifolds because the distance between the end of the exhaust manifold studs and the frame was not large enough to remove the manifold.
Today I removed all of the old studs (engine is now out of the car) with the intention of replacing them with new studs and I started thinking.
Why do I have to use studs, why can't I just use bolts?
On the one hand I can't think of an engine that uses bolts for the exhaust manifold, one the other had assuming the correct grade of bolt is used there is no mechanical or physical reason not to use them.
Please let me know if I'm missing something here?
