what is the head stamp code for the f22a1 and f22b?

thanks

 

Those are the stamp codes and the F22A1 is SOHC.

 

h23 is the DOHC prelude

 

Yes but you weren't asking about the H23.

 

honda made a f22a1 for the accord (90-93)that was sohc and a f22a1 for the prelude S dohc (92-97)

it might just be my info, here is the site i got this off of
http://www.hondaswap.com/forums/inde...howtopic=29825

 

How can one be SOHC and the other be DOHC when it has the exact same engine code?

 

I don't believe that is correct anything I have ever read inlcluding literature from Honda says that the F22A1 is a SOHC engine and it was not offered in Preludes past 96 models. 97 is 5th generation and has no S in the U.S.

The JDM F22B is a DOHC engine and basically it's almost identical to the H23 engine but with an 85 mm bore instead of 87 mm.

 

USDM 4th gen (92-96)prelude engines
f22=SOHC no-tec, S
H23=DOHC no-tec, Si
H22=DOHC v-tec, Sr-V or Vtec

 

ok im sorry, then i should ask what is the stamp code for the head of a f22b

 

That is the engine stamp code and it's not the the head it's on the block if it's a JDM F22B then it will say "F22B" on it.
