Any LS/VTEC's out there?

I am putting a ITR head on my 98 GS, but the problem is the cycliner head I brought is just a bare head. I need to get all the pieces together and take it to a shop. So far I had the valves, valve springs, retainers, vtec solenoid, rocker arms shaftsw/ pins and the lost motion assembly(What is it anyway). Cam shafts, cam gears and valve cover are on their way. What else do I needed? As for pistons, which would you guys suggest? I want to upgrade to Crown's rod. Do I use LS or Type R? Thank you.
