Love ya - mean it.
Your mods are almost identical. You start out with a 142.5 main jet, so you'll be going to a 152.5 as a starting point. If anything, it may be a bit rich.
Some folks with pre '03 LC4s have felt the need to richen the pilot circuit. This can be done by installing a richer fuel jet or a leaner air jet. You will have to decide for yourself if this is really needed.
