It took about an hour, but I am finally done, trammed it with a dial

Hardly done! G

That means it's off more than two tenths just over the diameter of a 1"
bit. That wouldn't give very pretty facing work.

But that's just my opinion.

This was the best that I could do.

I will try to face some piece of material and see how it looks with
the head trammed.

I do have a question, though: Since yours is a fixed ram machine,
how did you go about it? Did you follow the maintenance manuals, or
come up with your own technique? That's a heavy head, and when you
loosen the bolts, it wants to move all on its own.

There is a eccentric cam on one of the four bolts. This is what I
used.

I used one of those mills about 20 years ago. If I remember the feet
contact and adjustments on the floor also will affect how true the head
is.

You should be able to get it closer than .001" for a 4 inch sweep. You
should be able to face a piece of aluminum with a 4" flycutter without
any visible step showing between passes.
