[Jakins]

ive heard they are the same cast. I let somone borrow my civic and she burnt a hole through my head!! my friend has a d16y8 head and im planning on swapping the cam and rockers and intake manifold and whatever else I need to over to it. and im re building the engine. by the way. but if anyome can confirm this for me that would be sweet.
