[B]i own a 90 accord LX w/ a f22a engine
and does the JDM F22b head fit onthe F22a block
and if it does where can i find it

 

are you talking about the dohc f22b head? if so, i'm not sure where you could find the head alone...check ebay often and you might find one...i know there are a few vendors that sell the complete jdm f22b for like 500-600ish...for that price you might as well just not worry about a headswap and just use the entire motor..

 

it's the same head that's on the H23.

 

the head on the f22b dohc is a p14 cylinder head... Same exact head as on the h23a1... Yes it will fit...
