Racer Brown Valve Springs (need help identifying)

I was wondering if anyone could tell me what I have here? I believe the box says Racer Brown. Pics attached...very vintage, hard to read. I took one out to show it’s a double spring with a damper as well. Someone wrote on the box Hemi Valve Springs. Does anyone have any old Racer Brown paperwork? Just curious what they are good for? Thanks!

The outer spring is

The OD is 1.487
The ID is 1.04
Wire diameter is .201
Height is 1.950
Also has a damper in it.

The inner spring is
OD .985
ID .725
Wire diameter .123
Height 2.049

Thanks guys.

Don't trust anything written when it comes to older Hi Po parts
Take them to a good automotive machine shop or good Hi Po engine shop and have them tested so you know exactly if there useable or not
The original Racer Brown cam shop closed a long time ago, I'm thinking all the stock Mopar Street Hemi valve springs where 1.500 or slightly bigger, nothing smaller on the O.D.

Will do, thanks Cab.
