Dairian J Hogan

Hello all. I have a 1991 Honda Civic si with a d16a6, high comp, obd1 swapped, with a zc cam in it I believe. Or if that doesn't make sense it's a z6. I'm looking to upgrade my head to either a zc, z6, or y8 head. Don't know which one yet. My question is for whatever head I decide I'm going with crower v tec cams, wlike stage 2 or 3 vtec cam be better? Any help is appreciated.
