Seems reasonably complete as far as valve springs are concerned. I haven't been following the fuel injector portion of thread as carefully. Sometimes it's better to separate out complex threads into 2 or more topics
Miscellaneous supplies to have handy:
-- clean rags
-- cleaning solvent (lacquer thinner, or aerosol "carb cleaner", or similar).
-- gasket sealant if using cork gasket (mainly to "tack" the gasket onto the valve cover side, so it doesn't fall off). Permatex makes some non-hardening aerosol hi-tack stuff that's convenient.
And, do "one thing at a time".
ie, replace injectors & chip, makes sure it runs right, no fuel leaks, etc, before doing valve springs. Or do the springs first.
In scanning over the whole thread again, I note you don't list what other parts you have on your car concerning fuel delivery.
Many, if not most, people moving up to 50 lb injectors are also upgrading their fuel delivery to include one or more of the following:
-- Walbro 340 fuel pump.
-- "hot wiring" the pump.
-- adjustable fuel pressure regulator.
-- replace filter (and a tiny dab of anti-seize on threads).
What 50 lb Chip will you be using? Go EASY on boost and timing so you don't detonate & grenade the engine ... CAUTIOUSLY tune car with consistent gasoline quality & octane. It will be critical to have some good engine instrumentation, eg Scanmaster, accurate boost guage, etc.
I don't mean to be patronizing or condescending, but I just don't know how you're setup and it would be a major PITA to suffer a big Kablooie from over aggressive boost. It's too much info to cover here, but there are literally 100s of threads on tuning for the bigger injectors, higher boost, timing, etc. Good luck.
