Paying someone else to do it is almost the same as flushing the money down the toilet. If you're going nitrous, you'll want to go with a colder plug (ie NGK TR6). I believe most leave them gapped at .038. Just grab a plug gap checker when you pick up the new plugs. They're usually like $0.99 at the local parts store.

I think NGK's come pre-gapped. But its always a good idea to double-check. And shops will kill you on labor for a plug change, at least for an LT1, not sure on the LS1, but space is cramped on both. I've heard that some shop manuals tell them to tilt the engine a little for more clearance. So that takes some time. Just do it yourself. Getting around the stock manifolds suck though. Prepare to bleed.

No prob man. We're all here to help.
Just make sure you set aside some time to get all 8 plugs. Sounds like its your first time on this type of car, so it may take awhile. Access is not the best, so take your time.
I've seen cases where someone goes to change the plugs/wires, and they find that 7 of them have been changed before, but one of them (usually #8) is still factory, since its a Biotch to get to. And use antiseize on the new plugs too.

NGK's do come "pre-gapped" however i do highly recommend DOUBLE checking them... i didn't once and the car ran like shit... pulled the plugs and what do ya know... TR55's gapped @ .40 instead of .50 advertised... changed them all out and re-gapped then she purred like a kitten
TR55's are "stock replacements"
i recommend buying the TR55 iridium's (ie TR55-IX) though since stock plugs came with platinum's but then GM realized platinum's suck for our cars... have since changed to iridium & they are awesome
for changing out the pass side spark plugs it will be a challenge... just be patient and buy a 10mm gear wrench to get the coil pack bracket off the valve cover and you shouldn't have a problem... also don't be afraid to bend the ac lines (not too much though!) and the Secondary A.I.R. lines that go to the exhaust manifolds (but make sure they don't touch when you bend them back... the air line will rub through the ac line
don't waste your time going from underneath if you have stock manifolds/cats... especially if your an auto bc there is no room what so ever
don't forget anti-seize & di-electric grease
depending on mileage & condition of the wires I'd consider swapping them out for Taylor's
also Taylor fire sleeves to prevent arcing/melting of any aftermarket wires...
all can be bought from Thunder Racing

A new spark plug has been released for use in the above vehicles. The new spark plug has an Iridium tip instead of the current Platinum tip. Due to the different tip design, the gap of the spark plug has also changed. The new spark plug, P/N 12571164 with AC Delco P/N 41-985, is gapped to 1.01 mm (0.040 inches) when the spark plug is made. The spark plug gap is set during manufacturing and should not be changed or damage to the spark plug may result. Any new spark plug found to not be properly gapped should not be used.Last edited by 1BADDLS1; 04-03-2007 at 04:58 AM.

A stubby wrench saved me mucho time - of course didn't have it till my 2nd plug change. Stock plugs are pre gapped but double check them. Get extra gaskets for the AIR tubes that attach onto the exhaust manifold there super cheap and normally readilly available - you don't have to swap them but if they tear real bad you will need to install new ones (or you'll hear a tick) and you will want them on hand - few extra bucks now beats the old man it's Sunday and autozone don't sell that part routine. Best of luck and hope this helps.

I would gladly change someones plugs for $100. Once you do it a few times it becomes automatic.
