For my SM58 and my K3S I use the following:
50 Hz -16
100 Hz -16
200 Hz - 9
400 Hz 0
800 Hz 0
1600 Hz 0
2400 Hz +3
3200Hz +6
The Behringer XM8500 dynamic mike gives identical performance and it
costs only $20. Heard one and just had to try it. I can swap between
the SM58 and the XM8500 and folks that I rag chew with on a regular
basis can't tell the difference. Even the machining pattern on the
base is the same on both mikes. And in looking a the elements, they
too appear to be the same.

If one has a flat "wide band" mic (electret) the typical TX EQ settings
needed to emulate the Heil HC4 (DX)/HC5 elements, a couple classic
"communications" mics and a typical dynamic "vocal" mic (SM58) are:

Thanks to: <https://owenduffy.net/audio/legend/index.htm> for the
HC4/HC5/D-104/444 response curves. The SM58 data comes from
Shure's data sheet.

As Bob K4TAX has pointed out and K9YC has long advocated, set the
lower 2 bands of TX EQ to the lowest levels and set the 3rd band down
a bit as well - that will increase your "talk power" while not
wasting power trying to transmit those low frequencies which are not
needed for intelligibility. If you are into ESSB, you may differ,
but ham radio is not HI-FI in my opinion, it is about communications
effectiveness.
