Default Re: cast-iron welding ?

It should be good with the stock flat washer, if you don't over tighten it. The holes are over sized to allow the manifold to get longer and shorter. The casting should slide under the washers. I don't know the correct torque for these bolts, but a good guess would be as low as 12 to 16 pounds feet.
