Please post head codes from your Honda engines here
Members are often interested in identifying the head on their Honda engine by the head code.
HondaPartsHero has a thread here describing how to locate the head and block codes on your engine. The list below combines and updates the head codes posted in these two related 2004 threads: Thread 1 and Thread 2. I thought the large membership in this forum might further enlarge the list by posting the head codes of your engines. For example, my 97 Civic DX with a P2A-11 head was a new addition to the list.

Hey Ron, were you not aware of the list in Misc/Tech forum for D series?
https://honda-tech.com/forums/showthread.php?t=786093 This may be handy so people can cross reference casting stamps between motors (i.e. D15B7 has same head specs as the D16A6) Attachment 367572 |

Re: Please post head codes from your Honda engines here
I'll have to check my D16A (there is no number after the A, it's just "D16A"), which I was told was the JDM equivalent of a D16Z6.

Looks like D15B2 and D16A6 would be my speculations. What's the year stamp on the pm3-3? the pm9-3 is from a 91 as it's year stamp is '90.

I'm thinking being form a 91 car, the PM3-3 maybe the same gig as either B7 or A6 and will need to measure the cam lobes to know which one. The ZC with the PM3-3 is from 88 and would have a year stamp of 87 if it's original. I believe by 91 (casting stamp 90) the PM3's were used for the A6's and B7's. There is a pretty good chance that since it was before 92 though that they are A6 models. Cam lobe measurement will confirm. |
Re: Please post head codes from your Honda engines here
My cylinder heads say B25C.... I don't know what that means.
Whats the difference between PR3, PR3-1, PR3-2, PR3-3? |

Kind of makes sense, if they are casting in 4 different stations, and they find a problem with a head, they would want to know what station has the possible bad mold. |
Re: Please post head codes from your Honda engines here
Or perhaps it's the generation of the mold it was formed in. You may have noticed that all PR3-3 heads came from OBDII cars and PR3-2 heads weren't found before 1992.
Subarus do this same thing. USDM STI engines have a 70X number in the blocks. 701 is 04-05. 702 is 06-07, 703 is 08+. The one I put in my Forester was a 704 I bought from the dealer two months ago, so I think that was the latest generation. |
