How many here keep the coils on valve cover

The coil packs are pretty convenient on the valve covers - I left mine there. I painted the valve covers red with 2-part hi temp epoxy paint and put on new coil packs and new brackets. I like it because it's simple... however the look might not be for everyone.
The new valve covers and coil packs on the LS9 and the LSA engines look better than the previous setups. The coil packs bolt directly to the valve covers and gives a cleaner look.

1. will the upside down manifolds interefere with the plug wires? I heard they do, but would like to know for sure as that is the only reason why I would consider moving the coils
2. which manifolds are those?
3. does the manifold bolt upside down with no modifications?

One of the reason I asked, is cause I make these and sell them on e-bay.
I think there are people that put these LS engines in older car and want the look of the valve cover.

Call me crazy, but I kinda like the coils on there. Makes the engine look more modern. Note that these are truck coils and the coil brackets were very slightly cut down so there's only (1) bolt hole each. They will be lined up with the intake runner angle when bolted down tight.
I used a 6mm piece of all-thread that is locktited into the head with a nut tightened down at the bottom to lock the stud in place. Then there is a nut on the valve cover, the coil bracket and a nut on top of it. I'll snake all the coils wires down below the valve covers above the headers. The valve covers are stock ones that have been smoothed and laminated with C/F and epoxied.
Oh, you might also notice the mechanical throttle linkage setup and lack of fuel rail mounting bosses on the intake.

First 2 builds were left on the valve cover for a factory look. Next two are going to be hidden. I like the look of the valve cover and carb intake cause it is clean. A second thought on the brackets you show. There isn't much support fot the outer most coils. I would worry that they would vibrate and break off.

Thats actually kinda cool, I havent seen that before. I dig it. Although, Im not sure about the loctite in the heads tho, is there room for a jam nut and washer where the all thread goes into the head??

I plan on using the new Edelbrock coil covers without the edel logo and powdercoat them black and use some emblems from emblem pros. I just need to buy a new alt bracket that wont interfer like my vette bracket will.

I heard they do, but would like to know for sure as that is the only reason why I would consider moving the coils Yes, they interfere with the plug wires, but it's close. With a custom wire, you might be able to sneak them around the manifold.
2. which manifolds are those? Those are both truck manifolds. I have pictures of flipped CTS-V manifolds as well. They fit better and would allow for better turbo placement, but the plug wires still interfered. If you want the pics, send me an email and I will send them over to you. I might even have some pics of LS2 Corvette manifolds as well.
3. does the manifold bolt upside down with no modifications? Yes, they bolt up just fine with no mods.
