2005 g55 amg - 83mm pulley and Mbh headers?

I am planning to update the 5 belt pulleys and figured while I was there I'd do the 83mm SC pulley. I'll also do the BWK. I'll do the split cooling and upgrade the pump. Lastly I figured I'd upgrade to Mbh headers. wanted to gather everyone's opinion on if these mods would give decent performance gains while not causing any longevity or reliability issues. thanks in advance.
