No I have the Vortec 2 different EGR valves were produced the 2 links below are pictures of the 2 EGR valves that were produced for the CPI models. You will notice the difference in the way the electrical connector plugs in. They also have a huge effect on the performance. Having the wrong one caused my Blazer to misfire, die, barley idle, and it was hard to start.
