hey guys, i'm in the middle of putting together an f22b DOHC. i used the head gasket for an h23 and now im being told that i needed to use either an f22aX or try to source one out for a f22b. hoping i can get some input on this because i already mounted the head and i don't want to go back. when i put it in everything looked good and lined up so what the difference? will it work? thanks in advance.
