You want the B20 head gasket... you want the headgasket for which ever block you're going to use.No this will be like any other LS Vtec swap. Need LS Vtec kit, 94-01 GSR water pump and timing belt, B17 head gasket and new 94-01 GSR head bolts. While I feel the B17 is an over stroked under powered B16(it should have made more HP/TQ being bigger that a B16) I would want to keep the B17 motor in the original chassis. Honda only made 2,500 GSR's from 92-93 for the USDM (all JDM teg's had B16) so it is a rare car to find. I would just beef but the B17 with some cams and head work, bore to 1.8L and put some ITR pistons in + some tuning. That will get you some good hp and keep a rare car in one piece.
Sorry in this case you are right. The B20 has a 83mm bore and the B16/B17/B18 has a 81mm bore. So you will need a B20 head gasket. But it all other cases a Vtec or Ls head gasket will work just fine.
