Did some searching, did some reading.

One more thread for some opinions before I bite the bullet here.

Get GM O2's from a dealership or stroll into autozone or a place like that and get aftermarket?

Also, a few local GM dealerships don't have any GM exhaust manifold gaskets in stock. Do places like Autzone and Schlep Boys sell actual GM OEM replacement gaskets?

I got my GM manifold gaskets from Speed Inc. They were around 20 bucks. As far as the O2 sensor, Bosch and Denso are the only O2 sensor manufactures to speak of. I purchased corvette rear O2's when I did my headers fom Autozone for I think 75 bucks each. They come with a longer pigtail and supposely have a better heater. I have had ZERO issues in the last 4 mos. With no tune, my Ltrims are right around -5%.
Autozone carries the Felpro manifold gaskets, but they are paper core with metal cover. I personally would stick with the OEM gaskets. Hope that helps.

GM O2's. I've had the Bosch #13111 from autozone and now run GM O2's per recommendation from Speed inc. They said the fuel trims were all over the place with the Bosch's.

Ok, I'll just have the GM dealership order me up some manifold gaskets.

I was tihnking of getting the O2's from the dealership as well but I don't know. My O2's work fine now, I just might get some extender wires.

Actually just snagged a set of O2's with 10K miles on them, rear vette ones for $25/piece.
