Where are you buying it from? Can't you ask the person/company to be more specific?

And I agree with riruiz_88 that you should get a newer D16A8 or JDM ZC. You can get the ones from early 1990's for a few hundred bucks. I got one for free, full conversion <lol>
They pull well for what they are and have a nice torque-curve compared to the SOHC VTEC engines.

Are you paying for labour in the conversion? Coz labour could be close to $1k and you could always try to get a B16A
