Tuning question egt temps?

[bonesfab]

I have a Camaro that has a blown 406 with a fast unit. The problem is the egt's go to 1400+ just cruisin down the road. High vacuum conditons and advanced the timing to 40 deg. You can fatten it up till it blubbers and still gets warm. a/f is 13.5 Anybody have any sugestions besides cover the the guage....
