Recommendation of good spark plugs on a series one motor?

Looking at these. http://www.autozone.com/external-engine ... 86210_0_0/

Also, not sure if Bosch effects this motor or not.

Due to experiences with Bosch plugs, I will never use them in any car I own.
The ACDelco plugs you linked are what I put in my 93 SLE.
Nothing to dislike about them at all.

Previous owner had Bosch plugs in my grandmas 1994 lesabre. Not even 400 miles on them and they were misfiring. I had always used NGK V-Power #3951. They work for lots of GM cars. 3.8, SBC, N* etc.

They are cheap. I've used them in over a dozen cars and never an issue.

I like the NGK's but I currently run Champion coppers RS14YC6 and the car runs like a champ all the time.
