Does anyone know the factory inlet port size for vr4?

Iam trying to confirm what head is actually on my car. I have taken the inlet manifold off and have come up with these measurements.

37.5mm x 61.0mm this is taken from the very outside edge of the port.
34.20mm x 60.2mm taken with the calipers hard up against the face of the head ie inside the port.

Its definitely not an evo head. Just trying to see if its a vr4 or hyundai one.

Thanks guys!

Sounds like a VR4 head, the set of measurements that you posted in the other thread match my apsec inlet manifold perfectly.

Cool, Thanks bud! Now to remove all the sludge. Its very gluggy, dry type sludge so im pretty sure its left over from when the egr valve was leaking into the inlet. All fixed now so time to give it a clean up and slap it back together. Then I will be changing to a 2g timing map and going to all the specs ecmlink recommened and go from there. Should've done it from the start but it was in the shop for about 5 months so wasn't up to me at the time.
