Weight of Small Block Chevy Valvetrain Components

How does the "modern" cold stamping process, inferior metalurgy, and subsequent poor quality product figure into your calculations?

Which rocker? OEM non-rail, OEM rail type, PVS (Precesion valve systems), Crane Nitro?

What size valvespring are you looking for? 1.250"? Larger is possible and still comply with the rules. Behive should be considerably different in weight.

What size retainer are you looking for? Behive should be considerably different in weight.

Stock steel retainers (what valve spring size?) or chromoly or maybe the new machined tool steel (lighter than chromeoly, almost as light as titanium)?

Solid lifter, hydraulic or hydraulic roller? What lifter, standard replacement, Schubeck with puck or Schubeck with all composite body? Tool steel lifter body?

What pushrod? 5/16" 3/8" 7/16", maybe 1/2" per the new rules? Chromoly or standard?
I haven't seen the new rule so maybe by now composite pushrods are legal (just like composite body Schubecks are legal).

What valves? Hollow stem or standard? Hollow stem of course would not be legal. At least Inot that I'm aware of.

The devils in the details!
