The parts you listed will work but you'll also need an Alias poppet to go with that Alias ram you're getting.
And the 2k5 front block will physically fit, but it is not a direct bolt-on mod. THe retaining mechanisms are different for 2k2 and 2k5/Alias blocks (at least the one you listed there - there's an exception with the 2k4/2k5 Empire block). While 2k2 front blocks use a screw that goes into a threaded portion of the block itself, Alias blocks are not threaded at all.. rather the bodies are threaded for a large grub screw. You'd need to have your body drilled and tapped to accept this grub screw.
