my recent f22b dual cam motor took a crap on me, picked up a f22b sohc. but am missing a few parts from the swap, my question is what all parts are interchangeable from the h and f series, thanks. Need the following; fuel rail, downpipe and distrubutor. thanks in advanced! and as far as the downpipe goes its to the header that has the 2and3 exaust ports close together instead of evenly spaced.

 

The distributor should be the same, but I doubt the fuel rail would fit. Downpipe might fit.....

 

downpipe doesnt fit, nor does dizzy, dizzy from h23a1 and does not come close to bolting up.
