New LS1 Owners - Newbie Tech - Finally Got New Parts!

So my wife decided to let me get some new parts, i got some Lakewood LCA's and Motive 3:73's so now im wondering what im up against when it comes to installing these items, any input or advise from the pro's here on LS1 Tech?

Thanks!

Well the gears are not cheap to have installed but u can do the LCA yourself.
