Best Top 10 Bolt Ons For a 318

I'm gonna be doing some of these mods later this month on my (b body) 78 fury 2 door hardtop, with (of course) a 318, a 2 owner car, (I'm that #2 owner, had since 2007) 56k original miles, needs a lean burn ectomy badly. It actually ran pretty good on that lean burn til Middle of last summer, it now pings at odd/weird times which I attribute to that box on the air cleaner.
I have
A set of fresh from the machine shop #302 heads I wish I'd have cleaned up the rough edges on the castings before I sent them in. will do before the install
A couple of different aluminum 4 bbl intakes, a Performer and an Offy
A few different 4 barrel carbs in the attic
A brand new melling SPD25, which is stock replacement 360-2bbl cam
A set of new from 1984 DC small block lifters
A couple of small block electronic ignition distributors
A couple of new from back in the day, us made Niehoff 4 pin Mopar ignition boxes
Enough gaskets on hand for the job
I already have put an Edelbrock true roller timing set on about 10k ago when the original water pump went, because I was "only 4 bolts away" at the time. I was getting afraid of the aging nylon cam gear teeth at the time.
