I will try and comment on all your inputs, thanks for scratching your brains.
First off I made a template of the inside of the valve cover.
There is a lot of room under the aluminum cover.

Also that head is off the engine now and I am moving the springs over to the next head.
Rusty:
Stock rockers will be tested on the new head, same tests.
It ran great with the cover screws loose, I posted a video of it running on all 6.
I see no interference under the cover, the adjusters or tips don't touch.
408 Swinger:
The problem head was heavily ported and repaired by a pro where the water jacket was ported into. On number 1 and others. It has 1.88 Intake and 1.5 exhaust valves. The first valve cover stud is between the #1 Exhaust and Intake ports. Right between.
Rick C:
Head was off yesterday. I will do a test with stock rockers as soon as it's back together.
