Does anyone know or has anyone measured the diameter of the exhaust ports on the V6 engine 2005-8 at the manifold face of the head?

I purchased a set of 1 5/8" headers off ebay and when they came they were really 1 1/2" headers and the hole in the port face of the flange was only 1.344". That seems really small to me. I returned the headers because they were not as advertised, but if the port is really that small maybe that size would work better than a larger one. Since I was returning the headers I did not take mine off to see what size the port in the head was.

Has anybody measured theirs?

A lot of you seem to be doing header work on your V6. Could someone please measure the exhaust port diameter on the head and post the result? I would appreciate it.
