Do you have a smaller SC pulley not listed? I assume so by those plugs in your sig????

If not, you should be using stock plugs and stock gap. You might need to update your sig to help out the topic here.

My plan is to do 3 things at the same time, headers, 3.4" pully, and a PCM.

At that point, one heat range colder than stock at .055" would be the proper gap.

Read those posts and I think I'll go with these when the time comes. Its a big money saver, but I understand the headache with these...and I'll need help. I don't have a welder, grinder, etc etc.

So I either take these with me to WCBF and have nice people like willwren and boosty help me, or I drive to Intense and pay them to take the pain for me.

I dunno, SLP'* were downright awful to install on my 98...so it can't get much worse.
Those things made me scared of 3800 header installs.

SLP'* were cake on my 97 which should be the same as the 98. Remove old manis/DP/cat, add w body dipstick, then install the back header, cross over and front. Poof.. it'* magic.

I did something wrong then. In the past so meh.

I'm probably gonna go with Pacesetters anyway due to the cost. Its hard to justify $800 for headers a 2nd time around. Pisses me off that my friend with a 5.0 can get headers for $199.

I'm not dissagreeing with you, everyone has their opinion as to what works best. The reason I chose those plugs and gap was the info I got from intense racing.

Use Autolite® 104 spark plugs (two heat ranges colder than stock) if you have a 3800 Series II or III engine with 6 to 12 pounds of boost. At this level, we recommend reducing the spark plug gap to .050", or .035" with nitrous oxide.

That is where my car will be very shortly. I needed new plugs and I saw no reason to change then twice. I hope to order my SC pulley next week as long as my wife dont find my extra money. After I sell my telescope I plan to use part of that money to get headers, PCM, and possible a pillar pod and a aeroforce scan gauge, Also considering changing my front breaks to 12" rotors.

Yeah you should be fine with those plugs if you're putting a smaller pulley on soon. I went with the 104'* at .055 as well.

Ordered my new 3'4" pulley and it should be here later this week. I should have time next week to put it on. I also plan to order my new PCM this week. Is there much, if any difference between the different places? I'm planning to get this one, http://<a href="http://www.wbodystor...p-198.html</a> ZZperformance also has one that'* $10 less, but the core charge is $90 instead of $50 and I was kind of thinking about keeping my old one as a back up. Intense also has one for the same price as the one I'm looking at, but with a $50 core charge. Is one programmed a little better then the other?

i really wouldnt recommend the ZZP PCM
