im just wondering is there any difference in the F22B1 head and an F23 head? as in internals. im just wondering if i get parts for a f22 will they also fit in the f23 head? as in valves, springs, retaineres, etc, etc. if anyone has any info they can share tht would be great. thanks

I believe that the springs and retainers are the same. from what i remember though the intake valves are slightly larger diameter on the F23. possible they are the same as some H-series valves..

i've got a spare F23 head laying around that is half torn apart. if you need to confirm any specs or measurements let me know.

 

i just wanna kno if the F23 head will fit on the F22 block no prob. and im gonna replace all the valves, springs and stuff and just wondering if the F22 and F23 head internals r the same.
