I've heard to use an old spark plug, break off the porcelain and screw it in. Same for anyother bolt if you have a couple big enough. You can also cut off the oblong pieces on the smog tube, flip them over and bolt em down. They wont' leak, been done by many for years. If you want to spend $$ use the plugs mentioned above.
When I dissconnected my smog pump, I left the metal tube that runs around into the back of the heads. I'd love to be able to get to the bolts that hold them in, but can't. I wan't to remove that ugly pipe.
