The driver's side bank is quite a challenge with the supercharger application obstacles (2-3 hrs not including the passenger side bank). I have the Magnuson and I'm impressed the design allows reasonable access without having to remove much. For a snugger connection fit I internally taped my 1/4 and 3/8 sockets, 1/4, 3/8 and 1/2 extensions and ratchet connections preventing them from easily separating and falling into the abys (necessary due to the maze of obstacles the supercharger components introduce into the confined space. Recommend proceeding on a full stomach!
Tape is a good idea. Did you use a universal at the socket? It helped me when I did my RT’s plugs I haven’t done my HC yet, not looking forward to it…
I used a universal on the passenger side but wanted more rigidity on the drivers actually going to a short 3/8 to 1/2 inch adaptor as all the plugs were tiiight despite the appearance of anti seize. Don't recommend wearing any type of glove and possibly dropping a coil screw or a tool used to remove same. Be curious to hear how your application goes.
