There is no such thing as a B15B1. Perhaps you mean D15B1 which was the STD engine. And I assume the other one is the HF engine. The head would work, but you still need to use the MPFI distributor. But the HF and STD engines were both dogs and not worth the effort to do this.

well its in my race car and it suppose to be stock soo i cant really go doing a swap i allready did from a ew1 to a ew3 the d15a3

You can't do that. The D15A3 is the third generation Si engine which runs a vacuum advance distributor completely different then the 88+ electronic advance distributor (it also mounts differently, as you noticed.) The entire car would have to be reworked to OBD-0, which is absurdly difficult. For all the time you would spend doing that, at least make it worthwhile by installing an 88-89 D16A1 (Integra engine.) Similar results will come from an 86-87 D16A1, with no need to rewire the entire car.

I thought about doing the same thing to my car a while back, until I figured out just how difficult, time consuming, and expensive it would be considering the very minor power gains.
