I have a D16Y8 bottom end with SRP 10.5:1 c/r pistons and a D15Z6 head. Yes D15Z6 not D16Z6. The D15Z6 was a OBD2 head offered in Europe from 96-00. I am running a MLS Y8 headgasket, 97 Civic dizzy, and a Y8 timing belt. Is this all right?

The problem is that it smoke a little bit. The motor has been fresh built and the head had it's valve seats redone. The head has D16Y8 valves in it, but they went right in so I assume the D15Z6 is the Euro versio of the Y8.
