Valve Spring id Help Needed

[74desertduster]

So I have this complete set of new valve springs and retainers but don't know what they are. They came with my 360 and the guy said he knew they were Mopar but that was it.

Single springs.

Dimensions are:

OD 1.440
ID 1.080
Wire diameter .180
Relaxed Height 2.370

Can anybody help or do I need compressed info as well.

Thanks!
