Thanks guys. Very helpful!
I'm liking the valve cover bolts. Good find!I just purchased all new bolts for my set up as I removed my Eaton for powder coating. I'm went with stainless steel Allen head bolts, but this company also has the black oxide bolts. They have everything you need, but it's good quality bolts (like ARP) so, it's not going to be the cheapest either.
However, their customer service and shipping time is great!!! Everything arrives in labeled packages and they send out a goody bag with stickers, pens, magnetic calendars, pocket hand sanitizer, etc. Pretty cool as no one does that anymore.

Keep scrolling past the 03/04 specific stuff and you'll see the 4.6 specific stuff (i.e. tensioner bolts, water pump bolts, etc.).
Here are a couple pics of my new valve cover bolts:
