Do headers at the same time, kill 2 birds.

its spark plugs man, wtf do you need a tip for? Pull the wire off, 16mm socket, unscrew counter clockwise, gap new plugs, anti seize the threads, di electric grease on wire terminals, push back onto the plugs.

It isnt rocket science. Squeeze your arm/hand in there and do it.

first trick is to get an LS1 and put it in there

but seriously, its a bitch the first couple times. especially #8. if you have stock manifolds, try going from under the car

Tip: tie new wire to old wire before pulling it out to route the new wires on the passenger side otherwise you'll be swearing up a storm to get the wires through the open area to the opti.

Have you ever worked on an lt1? It's absurd how cramped it is.

I think he is hinting at the fact that posting about it isn't going to make it any less cramped.

After the headers and new plugs are on, for the next time cut a 5/8 spark plug socket in half and use a 3/4 wrench to loosen the plugs. With headers installed I could change all 8 plugs in 15 minutes from under the car.

nope, no real tricks to it. I used to do the superman on the car with my chest on the intake. That was the only way I could get to the back ones (had a 96Z). God I don't miss that part of the car. Nowadays I laugh at LS1 guys who bitch about spark plugs, damn is it so much easier vs an LT1. Luckily my Impala has a lot of room tho. That's the only LT1 car that actually has space to work with haha.

Having headers does make it a lot easier though. Manifolds leave you with roughly nothing to work with.

It actually is...they are literally "tucked" in there.

Get a Hayes or Chilltons manual if your at a total loss. They won't give the way with all the tricks but will give you a way to do them.
