changing spark plugs

any hints or tricks when replacing the spark plugs on a 2003 chevy astro 4.3
any help would be appreciated. thank you

Raise and support the front of the vehicle and remove the wheels. You can easily access all of the plugs through the wheel wells. A spark plug swivel socket, a ratchet and some extensions is all you'll need. Use AC Delco plugs ONLY!

Hey I have a quick question while we are on the topic of spark plugs. Old Master mentions "only" using AC Delco plugs.
My question is: the plugs that I get that are AC Delco, should I get a platinum, regular etc. If I get a regular, I am told to gap them .045. Is that the usual for the gapping?
What are the best plugs under the AC Delco lineup to get for a 92 4.3L vin W?
