Hi brick. I have the same car/engine. I replaced the original plugs, installedat the factory, with Bosch Platinum #DR9BPX. Getting plugs out/in on the rear-bank was .......challanging but I have long/skinny arms. The AC Delco brand plugs are very good, I just wanted to try the Platinum ones and I'm happy.

I've been looking for this kind of thread. I'm planning to replace my spark plug and i happened to open a site on accel plugs performance parts. I wonder if they have the spark plugs that is suitable for my 1987 cadillac.

I also used Bosch Plat plugs (#6241). A little grease on the arm is a help on changing the rear-bank plugs. I'm happy with their performance.
