Default D16a6 or D16y7 head?

Does the D16y7 (96-00 non-vtec) head have bigger intake and exhaust ports than the D16a6 (88-91 Si) head?

Thanks guys.

Is it the same as the D16Y8 head except with no Vtec? If so, the intake/exhaust ports are bigger than the D16A6 head.

Would you happen to have a set of D16A6 Pistons or a 96+ GSR distributor? I don't really know what you have, list some things.
