If anyone has this setup i was wondering if there are any issues, looking at it today i noticed that the O2 sensor on the Z6 header (dc 4-1) is near the cat end whereas the stock O2 sensor is kind of in the middle/top part. It doesnt seem that the wire will reach over there without being modified somehow. Any advice??

most (i can't say all, 'cause that would be dangerous) SOHC d-series exhaust manifolds are interchangeable. i have the stock manifold from my 1990 Civic Std. Hatch bolted onto the d16y7 head i have in there right now, and it is fine. extend the o2 sensor if you need to.
