I also had to elongate the LS adjustable motor mount plates by 3/4". The issue I had was that the coil pack on the passenger side was about 1/4" from the fire wall and felt this was too close. I made the parts work but would do a little more research the next time.
My coilpack was in the same spot as yours if not a little closer to the firewall. I made new brackets to move the coilpacks down and rotate them forward for clearance. There are a few companies that offer relocation brackets that would work great on a truck application but I'm running a car intake so I had an interference with the fuel rail inlet as well. Here's what I came up with to remedy the coilpack/firewall issue
