I'm using the SS fire-sleeve pass throughs from ACS you've mentioned. I ended up with one of each size. The interior firesleeve eats up a lot of space. The #2 battery I bring through the existing hole which I enlarged for a bulkhead fitting. The smallest SS pass-through I've got on the top-left of the firewall and will be using for ignition related wires. The 3/4" pass-through I've got in the little slot designed for the heat boxes and alternate air door. The 1" pass-through I've got on the upper right for all the thermo-couple wires and various other engine monitor wires. Van's has you drill another hole for a bulkhead fitting if you position the manifold pressure sensor on the inside. The existing hole on the far right I probably could have used for the 1" SS pass-through but didn't, thinking I would use it for something else. I'm going to plug that one.
Also, if you happened to drill the holes in the stainless recess according to the plans (as I did), you'll find that most of the nice pass-throughs for prop/mixture/throttle cables won't fit because the holes are too close together. I found these on ACS which do fit. I installed them just the other day.
