HO cam swap on SD system

What is the procedure for correcting the injector firing order for a HO cam swap?

No need to do so on a Speed density system as it is a Bank fire system not a sequentially fired system as the later injection systems.

I realize that it is a bank fire system but I thought that the different firing order required a different grouping of injectors for firing to match.

The injectors are grouped the same (1,4,5,8 and 2,3,6,7) on both the 302 and 351 speed density systems.
