Its hard to see but the opti spark has the cylinder numbers on the same side that the plug sockets stick out.

Passenger side top to bottom: 4,6,8,2
Driver side top to bottom: 5,3,7,1

Firing order for all small-block Chevys is 1-8-4-3-6-5-7-2

On the opti:
driver's side, top to bottom, is 5-3-7-1
passenger side, top to bottom, is 4-6-8-2

On the engine:
driver side, front to rear, is 1-3-5-7
passenger side, front to rear, is 2-4-6-8.

Hope that helps.
