Are you using a torque wrench?
Have you torques the camshaft cap bolts down in the correct sequence?
Both of the above are crucial

Torqued it to tight and ovaled out the camshaft seat... Besides spending the money to have it milled out, anything else I can do? Is $160 worth milling it?

How did they determine that ?

This doesn't make sense.
If you ovaled the camshaft bores, it would be lose in one direction, normal everywhere else.
The bores are much, much softer than the camshaft journals, so the camshafts should be OK.
I can see if you over tightened a camshaft cap that maybe you could distort the cap and cause it to wear in one area. But I don't think it would reform in another area to cause tightness.
Are you using the stock camshafts that came out of the bike ? Have you mic'd them ?
What happens if you put plastigage in the bores and install them, including torquing them down ? The shop manual covers doing this. What do the clearances look like ?
Any chance your head bolts are loose or your head is really warped ? Ever hydrolock the engine ?
What torque are you using and what torque wrench are you using to apply it ? Seems mine were 7 ft lbs, 84 inch pounds ?
