does anybody know the codes for all the b-series head?

The GR-R is P72 gen 3

The IT-R is P73 gen 3

The CT-R is P73

The Civic Si is P30

The P73 refers to vtec integra and the PR3,PR4 refers to vtec civic on almost all the parts except the cams they are the same except in the Si civic which is P30.

thats not a complete list, but its a start there are more, but thoes are the only ones i can confirm

The little I was able to find out with a few quick searches.

PR3-X = B16A/ITR family cast
PR3-4 = B16A
PR3-3 = ITR

PR3		1989-1991 Integra XSi/RSi
PR3-J00		1992 Integra JDM B16A EF 8/9
PR3-J51		1992 Integra JDM B16A EF 8/9
PR4		1990-1993 Integra LS/GS
PR4		1996-1999 Integra LS/GS/RS (B18B)

He's asking for the head code, not ECU..
as far as I know:

B16 and ITR heads: PR3
GS-R head: P72
B18B head: P75

A while back I bought a vtec head on ebay. I needed a 99-00 si head (pr3-4) and I just notice that it is a pr3-3 head. I got a little worried and didn't know what this head was.

the PR3-X <---- that number is not important..just check the year stamp, that says a lot

[P0gKai]

Well, remember that the production year and the model year is not the same. My '98 EX should have been produced sometime in 1997 for example.
