Will these springs fit?

Will these valve springs fit in unmachined LG4 (416?) heads? Also, would I use stock size retainers?

Comp Cams Single Valve Springs - 1.250'' Diameter Single Outer Spring w/Damper.
Valve Lift up to .490''.
110# @ 1.700'' Closed, 285# @ 1.250'' Open,
Coil Bind @ 1.130''.

Yes they'll fit.

Yes you'll use stock size retainers, however don't use the factory rotators.
