Installing a set of long tube headers makes it easier.
Were you using a standard socket or were you actually using a spark plug socket? A spark plug socket will let you get a wrench on it rather than just an extension, can be very handy.

Thanks!
This'll serve as a bump though. Sometimes you'll get a quicker response when others see that the post has been responded to.

Get smaller hands!! 
The LT1 motor is a much tougher job than the L98 to swap those two plugs. I used a ratchet with a swivel head and a small u-joint extension on the spark plug socket. It took some perseverence, swearing, walking to the other side of the garage to pick up the wrench I tossed, and one beer per plug!
I thing the A/C box is larger on the later cars so there is less room to work. Hopefully the plugs will not be too tight and you do have to remove them when the engine is cold otherwise you may risk stripping the threads in the aluminum head.
Use a good antisieze compuond when installing the new plug and torque them to spec or as close as you can if you can't get a torque wrench in there.

I just changed the plugs on a '91 and I was able to get to all of them. I did take the inner fender well off on the passanger side which wasn't that hard. I also used a plug socket in which I was able to get an open end wrench on the 8th plug and not the ratchet. I also used a universal socket at the socket end to make the turn on the front end. Took about two hours. Getting the boots off was harder than some of the plugs. Take your time and remember there is such a thing as necessary cursing! 
I agree with C4 Cruiser, use anti-seize for the future. Also be carefull with the Alum heads. I used an old plug boot to start them and when the boot began to slip, I used the ratchet to finish the job at 1/8 a turn more which equates to about 15 lbst.

I just did mine yesterday on my 95. For #8 I had to use a pair of pliers to put the plug socket on the plug. I then used a 1/2" wratchet with a shallow socket over the end of the plug socket. The whole job took me 2 hours and 1/2 hour of it was spend on #8.

I've changed my plugs enough to learn that , for me, doing 6 & 8 is just easier to get from underneath the car. I use a stubby 3/8 ratchet with a swivel head (Sears). There is enough above the starter that it becomes very easy. However, I have JBA shorty headers, so this may make a difference. If someone hasen't used diaelectric grease in the boots before, you are in for a fun time.
