93 SE, all stock. What type spark plugs would you recommed for this? I looked at NAPA website and they list about a dozen different choices with most of them being Platinums. Were Platinums OE or were copper core?

The Platinums are OK for the NA engine, I generally use copper plugs on all my engines. But I also replace them every year. But at about $1.30 each, you can't go wrong. autolite copper for me.
