check this out i was doing alittle cleanup on the old engine bay when i noticed the driver side header flange had a small crack in it. it starts from the top of the flange and its only about 1/8in long. pretty wide but looks like its not hurting anything. what you guys think replace or just throw a bead over it? its not close to the gasket so its not leaking but i have never heard of this? oh by the way they are bbk ceramic LT's bought about 2yrs ago.. anybody heard of this happening?
