90-94 EJ22 DUal Port -> OBDII?

[Wangan Wagon]

Hey there guys. I came across the opportunity to purchase some dualport EJ22 heads for $100 bucks in good condition, but my concern is if I can make the dualport heads OBDII to run on my stock ECU and with my Emanage Ultimate?
Considering this car is my daily driver too, I would like to keep the ability to know if something is wrong and what it is easily.

Dual port exhaust has nothing to do with OBD2. But you will need a new header.

what year/motor are they going onto?

up to 98 no problem
