Just change one plug or plug wire at a time and go on to the next one. As far as the firing order goes its right on the top of the intake manifold.
Someone will come up with a picture soon enough.

i found the picture but i am confused about how this goes does the white circle in the distributor mean that is cylinder 1?

I believe so but I am not sure, hopefully someone else will know. It’s been a long time since I did any work on my old 86 Burb, when we got the 94 Burb we retired the 86 to on the farm work only and haven’t had to work on it in over 3 years.

Yes, it does. You can put number one anywhere you want, just as long as the firing order is right. I used to put number one on the passenger side right behind the vacuum advance on the distributor. It really does not matter as long as your rotor is pointing to number one and the piston is on TDC on the firing stroke. On all V engines number 1 cylinder is the first one on the bank sitting furthest forward.
