those look good to me.
I just wish gm didn't have so many coils all different shapes.
I make some also. I sell them on e-bay. I had some request from guys to make one that fits the truck coils with the heatsink. They give out a ton more spark that the standard LS2 LS7 coils. I just made one that mounts the truck coils should have them soon. You should look at making some of those also.
