Sure it is not a exhaust manifold leak??

Sure it is not a exhaust manifold leak?? could be but when you start it up and turn it off sounds like simi air brake thats why i think upper intake gasket. i sure wouldn't have a therderbird.

Have you tried the spraying of carb cleaner or propane torch test to manifold for vacuum leaks?? Bad brake booster possibly??????????(Just a thought)
