The Stovebolt Site Forums The Shop Area Engine Shop Question about Rust pits on Intake manifold

Thanks,
Not sure I can get studs out but
What grit sand paper did you use? 40?
This is on a 283 and I did not take a spacer of
the engine when I rebuilt the Carb am I suppose to have one?The base of the carb was mounted to the intake with only a gasket seperating it.
