I memory serves correctly, I believe the dual extrude honing on the later SVT's took place in the heads instead of the UIM. Someone step in here if I am incorrect.
My main inquiry is the fact that my LIM is closer to the later SVT LIM in port size and I have an EO 98. I just thought it was interesting to have such a difference between the port size of the UIM vs. LIM. A little time with the dremmel will take care of this.
On another note, when I had the UIM off, there was no evidence of EH at all as there were several small casting bumps inside the intake. It was not very smooth at all from the factory.
