I dunno where to get Delcos beside the dealer, but sparkplugs.com has densos which are also a very good sensor for a pretty good price. Do you seem to be running rich at all? Because that could definitely be an issue with the O2 sensors and some have had issues with Bosch on our cars.

Have you logged the O2 output? Are you getting "lazy" sine-waves instead of picket-fenses? Are you getting a code?
Where are the O2's located (in the collectors?)? Hopefully you didn't put them farther down stream. If they go too far back they'll get lazy signals no matter how hot you keep them. Do you have a pic?

the car was a v6 I put an LT1 in so I plug under the dash doesnt work to read codes. I ses light comes on sometimes it does run rich. the plugs dont look to bad.
yes the car only ever had 2 o2s before the cat never 1 after. when I change them the car runs good for a while.

The sentiment towards Bosch O2 sensors seems to be overwhelmingly negative. Get some delcos. I've never bought anything from gmpartsdirect. Their prices always seemed very reasonable until you get to checkout and they hit you with some astronomical shipping charges.

^^ Most times the shipping charges were just fine. I've compared prices with RMS to GMPD and GMPD came out like $3 cheaper in the end.
However if you want your stuff in a hurry, RMS or SPDC. GMPD takes at least 7 days to get your order collected and shipped.

It may depend on the part. The shipping and handling for an unvented opti is 80.21 at gmpartsdirect. That's crazy. An O2 appears to ship for 4.15. I think you could still do better.

like I said there's also RMS autoparts (google them for complete addy as they're not a vendor on here) which has basically the same prices without the raping shipping.
One thing for sure is I miss Dal S.
