It might crack at the edge a bit, but it won't affect anything. The bigger issue is that the igear head is WAY too small for the TR body. There's another version of the igear set for the G1-colored e-Hobby exclusive, which might match the colors of the TR figure better.
Personally, I really like the TR headsculpt myself, though, definitely more than the igear replacement.
