Congratulations! I just finished re-installation after my first engine drop and Costa Mesa is near my old stomping grounds (moved to Austin from Laguna Niguel a few years ago).
I would implore you to ABSOLUTELY do the fuel lines. There's no better time - and there's such a PITA if not done now. In fact fuel lines are what lead to my drop and then a ton of 'while you're in there' items.
Some of the things I did:
All vacuum lines. Ordered Cohline 2633.1000 from belmetric for this line and phished it through (had to pull a foam block on the driver's side to free - then replaced this block. Might as well replace both).

Used extra bits of the 2633.1000 line to cut pieces for all the venturi/air setups that connect on the top left side of the motor and cut off the ear clamps and replaced w/ 304 stainless versions from Belmetric. Last thing I wanted was old rubber leaking.
I did rennline G50 transmission mounts as had less options w/ the G50
For engine - Wevo 911 SS mounts but w/ the black pillows as this is a street car and upon discussion w/ Wevo & Rennline felt these together would work best.
Gaskets, sensors, had Sean @ Tru6 Cerakote my fan, a local powder coater here in Austin do all the engine tin, and then sourced
Some mcmaster & other descriptions that might help you:
Vibration-Resistant Single Pinch Clamps, 304 Stainless Steel, 23/32" to 53/64" ID, for Firm Hose and Tube, Packs of 25 (for all venturi setup. J hose sourced from pelican along w/ everything I could find)

A20434 M6-1.0 X 12mm Hex Head Sems Body Bolts from Clipsandfasterners.com to replace all these captive washer bolts that secure all engine tin and a lot of misc items and are nicely zinc and beautiful going back in:

Franny / Heidi's incredible documentation in that whole series is fantastic as a resource - also make sure to clean electrical contacts w/ elelectronics cleaner - I spent ths weekend wondering why my engine was running on 4 cylinders only to realize all the original oxidation on the fuel injection harness was causing injectors not to get good voltage contact. Cleaned it and blew it out w/ compressed air and voila - engine running perfectly.
Best of luck!
