I have an overheating issue with my XJ12. I have new radiator from Jaguar, water pump, thermostats, hoses, belts, removed bypass pipes from heads, flushed the block, and heads, after sitting in traffic 100 degrees temp starts climbing way past half, a\c off, electric fans running on high, cool air coming from radiator, I'm still not flowing coolant properly????? I'm lost

Firstly, welcome to the Forums.
When time permits, please do an Intro in the New members Area.
That 1994 V12 would be an XJ40 and a 6ltr???
With all you have done I suspect a few things.
Thermostats are NOT closing the by-pass ports, common on the 5.3, but the 6.0 has a different set up from memory??
The dash gauge and/or sender are giving a false reading, VERY common.
A repost/reask in the XJ40 section will certainly get more answers than in this "general" area.
I will look at my notes etc later, but work summons at the moment.
