Big port??? Why do you want big port? If Mitz changed it from Big Port back to small Port on later heads (EVOIII) for a reason ... better off boost response & Torque....

If you get really stuck, They're pretty easy to find here in NZ. Not much difference in the NA heads either, as long as you get one from a 6-bolt motor, and change out the cams.
It's a dedicated track car, so the off-boost response isn't a big deal. It'll be making over 400HP ATW so the big port suits. I know the EVO head is good too, but as has already been pointed out, my existing manifolds suit the VR4 head.

If you want a Small Port head PM me.... :beer
im guessing he already has manifolds to suit?
i think aaron (1320ft) has a vr4 head ask him
I actually have a complete JDM VR4 here for sale.
Was running well (has has stock rebuild) when removed from the donor car.
