Lower end on my f22a6 went bad. Have an f22b2 in the garage. WIll the a6 head work on the b2 block? Any mods needed?

 

i havn't tried that specific combo yet, but i know those two motors are similar looking, and i know that the F22A6 head fits the F23A1 block with no modifications. VTEC and non-VTEC F-series have different length timing belts, but you're comparing non- with non- so it should be the same. i would recommend comparing the head gaskets and determining if there is any significant difference or need to use one instead of the other.

 

they bolt right on, i did it last year. no mods needed.

i used an f22a1 timing belt/tensioner, etc and it worked fine. i used the same setup on an f23 vtec bottom end.

easy peasy.
