05 to 06 head differences?

The motor is actually an 06, so that works out well for me. I thought there was still a short wire for the second plug (one plug on the coil and a short wire to the other). What changed between the covers? Are the mounting bosses for the coils just in different locations?

Edit: Well, nevermind the wire thing, just looked up the coils and I see what you mean. Hadn't see the dual coil on plug setup before, been looking at older engines too much I guess, lol.
