Brian,
Your missing my point. I understand that the DCI is a race head and KRE's head is a street & strip head, my point is both heads are made the same way and are made out of Aluminum. OK let me try this ......2 pairs of tennis shoes , one pair is a running shoe and the other a cross training shoe. Both are made out of the same material and each is special for it's own application...they should be priced about the same (or some where in the same ball park), get the picture.
