1982 spark plugs
82 owner. First of all, what spark plugs do you all recommend? I got Delco platinums, idk if that’s good.
also, how do you take some of these plugs off?? I don’t see how I can fit a wrench in some of these spots

Have you downloaded your vehicle info kit from the GM Heritage Center? It has a huge amount of info.
Stock plugs would be R45TS. Going fancy platinum, iridium etc isn't generally advised - just regular old fashioned spark plugs. I prefer the NGK brand; it's easy to cross reference online from the Delco numbers.

As per removal. Do you have good tools? A flex head ratchet? Universal joint in 3/8th's drive? Wobble extension?
Some of the plugs are much easier to get at from underneath. put your car up on ramps or jackstands and crawl under and have a look. On my 77 I can do all from above. But I have all the cool tools.

Plugs shouldn't have much torque on them. Hand tight and then a 1/4 or 1/8 (?) turn. You just want them snug. I use NGK plugs too.

My '67 is a breeze to change plugs but the '72 is a test of flexibility, tool creativity, and most of all pain tolerance. Like all things on C3s, the engineers didn't make any of these common maintenance tasks easy.
You ain't gonna get a torque wrench in there anyway, so tighten them until snug+ like resdoggie said. A bit of dielectric grease on the spark plug boots will help with the install and removal down the road so the boot doesn't get stuck to the porcelain.

On a stock motor, the 45s work just fine.

Take the platinum plugs and bury them....best use for them.
They are TERRIBLE.
Electrode too small
Gets covered in carbon 'splash' and fails to fire.
They are platinum 'plated' not actually platinum.
Not designed for your car.
Research BEFORE buying.
