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.

Right! It does sound out of time but it’s all timed correctly followed the guide I mentioned. All my timing marks align correctly. I spun crank a bunch of times and my marks always align correctly never got off. As far as the coil packs I can try to swap them around but it seems the way my wiring harness comes down it’s almost not possible to put them
In the wrong spot hahah anyways when I checked for spark I checked each coil pack and spark plug. Every single one of them was sparking when cranked and had metal touching it. Unless there’s a such thing as weak spark? I’m not sure at this rate
