Grill block or air dam?

Grill blocks can have the effect of limiting cooling, yes.

Air dams...well that's a tough one. I have heard of low air dams reducing the differential's cooling when under heavy loads. There was a thread about that very recently you may want to read. If it's a concern, just avoid it.
