okay i have a f23a1 head on the f22b1 block and my question is are the cams interchangeable from the f22b1 to the f23a1??? if so what are the differences in this two cams. the reason i am asking is i am thinking about getting the bisi regrind (stage2) but the only cam i have to send in is a f22b1 cam so this is my problem and i don't know nor can i find out if the lobes are taller on the f23 to where if i did get a regridded f22b1 cam it will make it worst than with the stock cam in it. any info will be great... i already sent a email to bisi to see if it will work or if he will regrid the f23 one(no word yet)

it bolted right on and when i got my felpro head gasket it said that it worked on f22b1 and f23a1 even though they are different piston sizes. but as for there being a gain with it i don't know because my car came with a d15 in it at first then i went strait to this frank, but i do know the ports are 2mm bigger on this head vs the f22b1. and now that it is running i am trying to see what options are open to me with this head and am not getting to far but as for the setup goes i am happy lolOriginally posted by bcjammerx View Post... didn't know you could put that head on that block...is that better performance or something? sorry i'm not help thereComment

94 civic vx hatch. it also has the prelude si tranny on itOriginally posted by customchord View Post
well i got on majestic honda and started looking at part numbers in between the two heads and it turns out the valves, cam, and rocker armes are different, but the springs,retains,caps, and other misc. stuff are the same. but i still don't know the differances in between these part other than the part number doesn't match lolComment

The f23a1 came on of a obd2 accord. Like 1998 or something so it could have just been changed over the years. But you could always get a delta regrind if there aren't any aftermarkets for those accords.-1991 Honda Accord LX H22a-

hell maybe some of these parts are inner changeable and would make a killer setup out of stock parts. i know if you change the rocker arms and the valves it might make a change for the better or worse but it is hard to tell and see what options are there if there is no info on these heads out there. but as for the valves i also know the the intake is like 32mm and the exaust is like 29mm(don't quote me on it i can't remember) on both the heads so for it to have a different part number i would think that it is the stem diameter or length that is different.and i ran across this.

true but if you don't know what you have how can you know what to get. and non of the regrinders metion the f23 cams and will probley give it a f22 grind which might hurt the power or not do anything for it in the end. i am just trying to investigate and look into the whole aspect of the head before i make a move.Originally posted by customchord View Post
and i thought it might be the obd2 crossover too til i looked up the 97 f22b1 and the part numbers still didn't match so that idea got thrown outComment

But the F23 is out of a different generation accord. The F22b1 has a completly different head compared to any other f series. Try looking up parts from a f22a1 or f22a6-1991 Honda Accord LX H22a-

i will i just thought the b1 was the closest in design because of the vtec operation and the port design on the exaust ports and these two are the only heads that can swap intake manifolds with no problem. and even when i look at the diagrams of these two heads they are the same just the part numbers are differentComment

Have you tried searching Honda-Tech?-1991 Honda Accord LX H22a-

i looked up the parts on the f22a(x)'s and non of them crossed over so i still don't know about the cam, rockers, and valve.
and does any one know the valve lash specs for the f23a1???is it the same as the f22b1 at .010 intake and .012 exaust???Comment

Stop. Just stop. You clearly don't know what you're saying.Originally posted by customchord View Post
The F23A1 head is most similar to the F22B1. It's not the same (obviously), but very close.
The F22B1 cam regrind MIGHT work properly. I would suggest calling, emailing, or PMing Bisimoto and asking the man himself. If you plan on going to him for the parts, I know for sure that he'll gladly help out... and I'm sure he would know what works. If he doesn't, he's not the type to guess.
