Spark Plugs

Spark Plugs
Over winter I'm planning on installing my Pacestter LTs, and I figured I might as well chage out the plugs and wires. Seeing that its such a challenging task due to space constraints, I figured I'd change out the plugs once I get the exhaust manifolds off. The problem is, I don't know whether to just get some good ole AC Delcos or upgrade. I've heard bad things about platinum or double platinum plugs on GM cars. (don't ask what, I can't remember, just that it wasn't good) Is it worth it to buy iridium plugs for a stock LT1? Or, I've heard from my mechanic, and a couple other performance guys that AC Delcos are the safest most reliable for GM cars. So, what are your guys opinions? What do you run?
P.S. I'm thinking MSD 8,5 mm plug wires also. Good? Any better?

Second for NGK-TR55's, i hear they are the best to use. Also if your looking for wires check out www.elitesparkplugs.com. They have many sets of wires that are nicely priced. Im about to purchase the 8 or 8.5mm with heatshields. Good customer service and they have what everyone needs.

Re: Spark Plugs
I'd also recommend upgrading your plug wires. I did when installing my L/T's and have not had one problem.
My brother installed L/T's on his LS1, and did not upgrade. He kept fouling plugs as a result.

MSD Wires though stock location. NGK TR55's are treating me good, but Autolites are a great brand too. I only went with NGK over Autolite since they were in stock when I needed them.
