I have a 1950 8N, front-mount with serial number 257XXX. It seems it's time for me to replace the manifold as hot exhaust gas (and an occasional spark!) recently started escaping in the circled area in the picture between the block and manifold. There is quite a bit of back-firing until the engine is completely warmed-up, but after 10-15 minutes, it runs pretty smooth. I'm guessing the leak reduces as the block and manifold get hot and expand.
I would appreciate any tips or advice prior to me tackling this one. While simple on paper, I'm guessing there are other parts I should go ahead and replace during this repair outside of the manifold, manifold/block gasket, and muffler assembly (the muffler pipe at the manifold is almost rusted through as well). It's probably best to replace all associated nuts and bolts, but I'm wondering if the manifold stud bolts will come out or not. What do you suggest?
Thanks for the help!
