hello i have 2 heads and was wondering if they were different in any ways? one has 2.5 stamped on it and the other has 2.5/2.7 stamped on it, are there any significant changes or are they all the same but different years?

Thanks

That head would only be able to be used on the Super ETA which mean's the 2.5/2.7 head is from 1988 or later. The reas on for this is that all the other 2.7's used a version of the 2.0 head which is a different shape. So yes the 2.5 head and the 2.5/2.7 head are the same.
