I'm replacing gaskets on head and manifold on 8N. I've found that the exhaust/intake manifold is rough and pitted on two ports. See photo.
It almost looks like this has been welded - but that would be impossible / improbable - correct? The rough area is not left over gasket - it is entirely pitted metal.
The gasket came off this area is bits and pieces - so this has been a bad - leaky area for awhile evidently.
Is it necessary / advisable to have a manifold machined? Is it necessary considering that there's not compression as there is on the head?
Should I just scrap / sand / file this down as much as possible and will a new gasket then seal this up?
