Bought a set of headers used from some guy. There seems to be a little damage around the collectors. Will this damage affect the seal? Sorry if the pictures are bad.
Damn straight it should work do both above posts
Get the surface as flat as you can
Spray the gasket you are using and the header flange with copper coat
I'd fill the holes slightly with some extremeheat JB weld, sand it smooth and then use copper gaskets. A little overkill, but i'd rather do the job once.
