The watepump Clint has and the one I have (LS3 from Camaro) are identical in layout except his is for a truck motor where the belt/drive is spaced forward from the block an extra 1.5" compared to the car pump. As far as I can tell, the only difference between the truck and car pumps is that the truck pump has the passage from the pump body to the block mating surface 1.5" longer.. the main pump body, pulley, inlet/outlet, bosses, etc, are all identical between pumps.

the video is in order for you to see if it is the right one, i cant tell which came off my 6.0 or which my 5.3... does it matter (whether they came off the 5.3 or 6.0)?, are the coils the same as long as its the round type? soon as i get up in a few hours, ill take the vid so you can see what im saying... some coils are the squareish kind and i have a couple round kind that look like what you need...

LSCustoms - Thanks for the video. I will have to double check what I have and I'll shoot you a PM when I figure it out.
A helpful member on another forum told me he had placed his coils under the headers like this with terrible results. He said he went through 3 burnt up coils in 6,000 miles before he moved them behind the heads. He said they have been doing okay back there. I don't really have room behind my heads due to the setback of the engine, but I have some other options I'm exploring instead of what I posted above.
First, here is the mockup with the coils in front / to the side of the heads. The plate is just a piece I had laying around that I drilled for this purpose, so ignore how unneccesarily large it is for now. There seems to be space on the driver's side where I could do something similar, but more to the side rather than in front of the heads. I don't really like this.
Second, here is what they look like loosely situated against the firewall. They just barely fit end to end between the evaporator case and the wiper motor. In this case I just stacked them on a piece of 1/4" allthread and laid them there to eyeball it - I haven't made any mounts.
I think that doesn't look terrible. What do you think? It has the added benefit of hiding the dent in the firewall some naive 17-year-old put there to clear an HEI distributor, even though his real problem was not putting the proper spacers in under the firewall body bushings. I wish I knew who that guy was - I'd give him a talking to.

I personally like Joe's coil relocation setup.
Man, I'm seriously considering switching to the L99 water pump. I'd love to get rid of the giant upper hose I have running directly on top of my inlet. But I guess that's what we had to live with back in the day.

Why is it you are moving the coils to a different location? Speedtigger bought the Edelbrock covers which look pretty good. Chevy406 mounted them on the hood hinges which also looks good. Not really liking the firewall mount as much as I did the under-the-header mounting. Leave them on the valve covers and roll with forward progress. First fire by Christmas?!!

Keep the opinions coming. I am torn. I don't like how they look on the valve covers as much as I realize long plug wires suck. I don't like any of the coil cover offerrings and I can't think of how I'd build a better set. I've looked at the Proform and Katch valve covers which mount the coils higher, but still have plug wires going over the valve covers. I've looked at the Edelbrock and Holley coil covers. I've looked at the Holley valve covers which I like ok, but I don't think the last coil on the passenger side would fit with the AC box. I've looked at full engine covers and partials like the Rotofabs, the stock Gen 5 Camaro, cut down versions of everything from GTOs to Holdens.
My personal favorite look is the GMPP "competition" covers painted black like this:

Clint, the GM factory race team, mounts their coils in an under header manner with great reliability. Personally, I'd keep the plug wires as short as possible.
