Wasn't there variations in emissions laws and/or engine models? Were they all the same compression?

the U and T reffer to emissions so as long as both engines are SED then the compression is the same as well as the no. of valves

Yes.....

T = TLEV ( transitional low emission vehicle )

U = ULEV ( Ultra low emission vehicle )

Basicly TLEV was the standard they put in place for a number of years before ULEV became a requirement

So TLEV was better than the typcial "C" engines ( such as C20XE, C20LET, C20LZ, C20NE, C20GET ) but it was still not as good as the current ULEV
