You can get the metal elbows anywhere, Dorman makes them. Not sure but ZZP usually is a premium pricing wise. Rockauto has em' online, autozone and advance auto has em too.
I always recommend if tearing the lim apart, that you might as well do all the fluids, including the tranny. Do a pan drop and replace the tranny filter too. Good time to do a shift kit if you want to get adventurous as its not too difficult as well while the tranny is open. Add Ignition wires, plugs, air filter or go open cone too while you're doing things. Take the throttle body of and clean it and the maf, only use maf cleaner on the maf. Coolant flush and replace the dexcrap is good time too as you'll drop most of your coolant doing the lim.
If you're keeping your plastic valve covers, the new gaskets... do not get them from ZZP (problems sealing correctly). Get the felpro kit as I think it has the grommets for the valve covers as well. Don't forget thread sealer, thread locker (blue) and copper RTV.
Make a list and be prepared before you start, have everything you need. Also note that a vac line here or there may break when you take things apart.
It all sounds like a lot but it's not.
