Changing spark plug with Header, not to hard job ? I never change plug on lt1 before, most lt1 I own the preview owner already change it. this 97 lt1 already come with shorty header, I think the passenger side header need to be tight. Nothing wrong with the car atm, no idle issuse, but I just want change the plug since the owner told me he just did, but I want to do it anway and not wait until it fail. Im thinking this sunday first thing in the morning, is get down their and change the plug with tight all the header bolt. I bought 8 ngk tr55 and gap at .050. and fuel filter, any tip on changing the plug with header ? I have tool, but what tool combo tool work best here ? thanks ! BTW any one know a " Jack Point " on lt1 car ? I need to know where best location to put the jack stand. Pix would be nice.

Even with headers it sucks. I have Hooker long tubes and I have to unbolt them to get certain plugs out cause there is not enough room to get a wrench and socket back there. If its not needed right away I would just hold on to the parts till they become needed.

Are you referring to #6 and #8? If so, a better way may be to get them from underneath. You'd still have to use a wrench on a plug socket, but it can be done. You can also use an offset box end wrench. A bit trickier, but can be done. I can't rightly remember, but the starter may have to be unbolted.

changing plugs with my lpp's is 100x's easier than with the stock mani's. No **** I could probably do it in less than 45 mins. Also I have the shorty slp spark plug socket and it made it a lot easier.

well guys, just got back change upper and lower radiator hose, then itchy about doing spark plug change, HELL IS COMING !! Im doing driver side first, im take all out at the bottem, and passenger side I take every thing from the top !!! take me 6 hours to just for plug change ( first time with lt1 ). its 2: 46am now, i need to sleep, body is cover with coolant and grease, i take a shower tomorrow, btw job cant be done without #19 wrench and spark plug shocket that let you use the wrench to turn, btw some time my spark plug socket stuck, any one have tip how to prevent spark plug socket stuck on plug ? I use delectric grease to put on spark plug so it kinda loose when I take of the socket, but most of the time it just stuck their with the plug. 
one last question, the preview owner using denso irridium plug, when I take it off, the tip of the plug seem coming loose, look like you can twist it in and out, is this normal ?

when my dad and I changed the plugs on the bird when I first got it, it took us about 8 hours to do plugs and wires. We were both like wtf it took us that long just to do plugs and wires? We've had the trans and transfercase out of my sonoma out and back in in that much time, though the car had the stock manifolds on it and we didn't pull the starter out either, that probably would've taken some time off, since we messed with the #6 and #8 plugs for a while. Since the long tubes I've changed them a few times and it's been less than an hour each time.

wow 100k miles plug. that way crazy, will delectric grease turn into those white powder thing after long period of time with plug ? is this normal ? few year ago im alway use delectic grease on plug boot, then after a year I take the boot off the plug, and find out bunch of white powder thing, I beleive its from the delectric grease. Will these white powder thing do any harm to the plug ?
