Alternative lower timing gears for head swap.

[EXkidd91]

I am looking into the f22b head swap and can't find anyone who has the lower timing gear. I've also searched around here and can't find anyone who would let one go without the motor attached. So what I'm getting at is at my local junkyards they have plenty of Honda DOHC's, Just now H's. Does anyone know if maybe the lower timing gear off the b18, or something would work?

has to be F or H series, the portion of the crank where the gear/pulley go has to be the same diameter. I'd try an LS pulley though, it couldnt hurt.
