From Honda-Tech, Head casting numbers:

93-96 VTEC Prelude: 12100-P13-000
97 Type SH Prelude: 12100-P13-000
97 Base Prelude: 12100-P5M-305
98-00 Base/SH Prelude: 12100-P5M-020

CD6 4D Accord Si-R: 12100-P13-000
CD8 2D Accord Si-R: 12100-P13-000
CL1 4D Accord Euro R: 12100-PDE-E00
CL2 Wagon Accord Si-R: 12100-PCF-010 (AWD DOHC H23A VTEC)
BB6 Prelude Si-R: 12100-P13-000

I found two for the BB6 Type S:
12100-P5P-305
12100-P5P-J01

I also found a 12100-P5M-010 for the Si-R. The second numbers appear to have come about at the same time the USDM p/n changed. I can only assume it corresponds with some minor casting change or similar.

To answer the original question, and for those to whom it is not obvious...

If you find a casting with a stamping of:

P13 = USDM H22A VTEC head or JDM Si-R 97 or earlier
P5M = USDM H22A VTEC head or JDM Si-R 98 or newer
PDE = JDM CL1 4D Accord Euro R
PCF = JDM CL2 Wagon Accord Si-R (AWD DOHC H23A VTEC)
P5P = JDM Prelude Type S or S-Spec
