This really sounds like a timing issue when you’re getting backfire (through the intake?), like when a carbureted engine shoots flames out the carburetor when the timing is off by 360 degrees.
Are you certain that you have the coil packs wired correctly on each side of the engine and not have them reversed? You can swap the connectors between each set of coils on each side to test this.
