I need a new header and see that there are some for all f22b's and some for vtec or non vtec. Is there a difference in the exhaust part of the head or is this all unnecessary?

Im looking for one for my f22b1

 

Your f22b1 has vtec, the other head (f22b2) is non vtec.

Will a F22B2 exhaust manifold fit a F22B1? - Honda-Tech

 

Im aware of the vtec differences which is really just seen with the intake valves. I was wondering about the exhaust ports, if there was any subtle differences. But I did find that second thread the day I asked this question and found a great answer.
Thanks.
