replacement valve springs for 83 318

Or more precisely does anybody have a goto set of cheap valve springs that are drop in replacements on 80s 318 heads for mild cams.

The cam would be small, tiny, itty bitty, lol.

Under 450 lift and probably 20x/20x duration.

It wouldn't require much valve spring at all.

I still need to pull the heads apart and measure the OD and installed height. But I figured that somebody might know off the top of their head. Thanks, Eric L
