It would be but if your manifold is cracking that easily then you might have a different problem and that problem might even crack a header so id do a more in depth search. Look at if theres anything hitting the manifold and or if you car is running to hot. If the crack is in different spots on both manifolds then id just get a header that way if it keeps cracking you just send it back and theyll send you a new one for free haha.
But if its in the same spot you maybe hitting something so check it out. More.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
