I think the firing order on any GM V-8 is 1-8-4-3-6-5-7-2, #1 being the front cylinder on the drivers side and #2 will be the front one on the passenger side, then back to the drivers side for #3 and so on.
Why do you ask as plug wires can not be crossed? Is the engine not running right?
The diagnoses said it is my #1 piston has a misfire
