Magnum Valvetrain, Valves, Springs

Have bare EQ 1.92 castings I'm looking to populate. Looking for stock rockers or maybe aftermarket, stock size valves, maybe stock springs (undecided).

Not trying to spend someone else's money, but you might consider some basic new springs like the 1110 Hughes stuff.
I don't think I would trust used stockers to close the valves before the piston gets there.
