Re: Six exhaust and intake manifold

I also have a '39 Six and have recently gone through the motor. The Intake and exhaust manifold does use a gasket. I had to have mine surfaced but had a difficult time finding a machine shop to do that, I have a milling machine so I set it up and fly cut the surfaces. In my case, I milled the exhaust and intake seperatley as the exhaust seemed to be pretty far off. When I went to reinstall the manifolds, I left the bottom bolts loose that hold the intake and exhaust together just below the carburetor. Once the manifolds were tight to the cylinder block, I tightened the bolts that are in the center, holding the two manifolds together. It worked perfectly and there are no leaks.
