440 Breakdown/Rebuild

Valve springs? 440 Source doesn't recommend using their springs for that camshaft. I would use Comp Cams 924-16 or 925-16. You can use either of those springs with the Stealth retainers and the replacement locks (is that what you are referring to as keepers?) you are going to use.

Probably the Ccomp ones they recommend, that or beehives. And yes, retainers.

Either buy a Milodon 3 gear drive or use a timing chain. Those floating idle gear drives are JUNK JUNK JUNK. Don't waste your money.

I liked the idea of gears over chain so there is no slop, and I am not a fan of the single unit because it needs the billet cover that is pretty ridiculously priced IMO. I've spent a lot of time on here and elsewhere and I haven't really found anything saying they are bad or anyone having issues with them, what am I missing?
