exhaust leaks

I have eight exhaust leaks on my 66 barracuda. It's a 318 unknown origin, with the 273 intake manifold, exhaust manifolds and valve covers. The problem is the little 1/4" smog hole below each exhaust port. The holes are not threaded. Does anyone have a cheap, in the car fix for this problem? Also, can some one tell me how to separate my text and pictures so I can label the pictures?
pic 1 is the front port of the driver's side
pic 3 is the middle port
pic 2 you can barely see the hole below the manifold.
