Hey, just had quick question.

Would a 2000 prelude head fit on a 2000 b16a? If so how would the performance be? would it help or hurt performance? thanks

 

Ive never heard of a H22 head on a civic, Im sure it doesnt fit...i have heard of an H22 head on an H23 though...

 

It won't work. The footprint of the Prelude head is too big to seal with the top the B16 block.

 

nope wont work the H22 & H23 are the DOHC "Big Block" engines from Honda you can swap between those only. The F22a is the SOHC varient. B-series motors swap between themselves and D-series between themselves only no engine swinging without lots of cash to do it.
This includes transmissions too.

 

Um, the F22 is definitely DOHC isn't it?.. it's in the S2000.

 

the accord motors are f22s as well, just not F22Cs.
