Well on many 3.1s in the GA'* you need to rock the engine to do it from above.

To give you a reference point, I run a .55 gap with the spray.

i suggest using a lift if at all possible. changed mine today on a lift and the back 3 took about 30 minutes too do(remember it was my first time doing the bonny'* plugs). tommorow it'* back to the lift to change the autolite 605 platinums out for the ngk t55'* i bought today. i gapped mine at .057 and i think i lost a couple of horses. but i'll know tomorow. i also suggest wearing gloves unless you enjoy getting battle scares. my hands got some pretty deep cuts in them today from the exhaust heat deflector

i have yet to do mine, my dad thinks its gonna be impossible. Im like 6'0" so I will probably just put a tarp on the engine and lay on it.

I just regapped mine this afternoon. Changed from .055 to .058 to see if it makes any difference. Took about 30 min since I wasn't in a rush. It'* a lot easier now with the brackets removed and the headers installed. I did chaiffe up my left arm a little on the damn heater hose clamp.

Notice any difference?
I still haven't put mine in yet, as I'm waiting to get paid this Friday so I can get some MOBIL 1 and a FRAM X2 filter as I want to do the GM Top Engine Clean and don't want to mess the new plugs up. I'm thinking I might just gap them to .058 so as not to go too drastic and if all is well I'll take it down a notch or two. Probably shouldn't do any big-time rodding until I get the lifters done, but Friday night will be The Addictions time to shine at Grove Creek Raceway. Wish me well.
