sorry guys your all wrong....the dc2 came with the b18c1 or the b18c5....you guys are thinking of the dc4.....

now if you realy meant dc2 than the blocks are inerchangable....not the same though you will need a tune. and the b18a1 head will not go onto your block

if you meant dc4 than yes the blocks are interchangable and you will not need a tune, and the b18a1 head will be fine just use the dizzy and manifold that are in your car to make it easier.
