I cut the AIR tubes off of a pair of '81 Corvette stock shorty headers and need to close up the holes. The tubes protrude inside the header tubes about 1/2" and I didn't remove that part yet. I'll leave it until I get the holes welded shut. These header tubes are cast stainless and the AIR tubes are also stainless. They are going on my '69 truck.

What's the best way to weld them up?

Mig with stainless wire? How thick?

Stick welder with a small diameter rod?

Take them to a pro and write a check?

Thanks for the help.
