Broken exhaust manifold tab / ear...

You can mill the exhaust manifold sealing surfaces flat and install them without gaskets.

If you are a DIY type of guy and want to save money, glue some 80 grit long and skinny sandpaper to the flat surface of your table saw.

You can get them straight and flat, it takes some time. You will see by the patterns when they are straight. Double check with a straight flat edge then install them with out gaskets.

Or take them to a machine shop and have them end mill them flat.
