it's "vtec"
i don't think you will be able to hit the stock pressure level, which is 38-46 psi with the hose disconnected. that fuel pump flows at too high of a feed pressure.
i think you'll need an FPR like this https://honda-tech.com/zerothread?id=2060118 which has a bigger bore return orifice to handle the higher feed pressure. what happens is the feed pressure of the pump is high, and the pump can't get the fuel out of the reg and to the return fast enough, so the pressure always stays high, probably in the 55-60 range.

same range- if you are around 40-42, you are in stock range.
