Ya you'll need to shim it out. every timing cover is different due to casting. my BGG kit didn't work worth a damn for shims so I ordered shims from McMaster-Carr
I don't have PN's for pulleys, you can source those on your own pretty easily. Just start looking up F150 5.4 8rib pulleys. I personally didn't use Ford stock pulleys as they're junk.. Go with Thump or American Racing solutions. I just built my 10rib kit for my car using American Racing Solution idlers, and a Innovators west alternator pulley.
