Piston Rings on straight-six
The piston rings are supposedly shot on the good old 6 cylinder, the guy told me I could probably get another couple thousand miles out of them before their gone. Should I just replace the old rings, get a rebuild, or just go all out and swap it for an eight cylinder?

I had the same problem with my 83 so i decided to do a complete rebuild. after reading numerous posts about both I6's and V8's i decided to stick with the 258. easy engine and rebuild will be less expensive.

check your compresion before you tear into anything. Sometimes, people screw up and give crappy suggestions. It never hurts to check it out first...

I second Mugs. Do a compression check. If the compression is better good after a couple of squirts of oil in the cyl., then it's definately bad rings. If the compression doesn't go up when you squirt some oil in there, then you need a valve job. I've heard of people that do valve jobs, and a few miles later they experience blowby because of weak rings. So doing a valve job only is a bit of a risk.
