Help! Source for Bolt Heads?

"...
What number do you have now? Gunparts lists stripped 0's and 1's at $12.90US each. Marstar lists 0's, 1's and2's. You'll need a No-Go guage and a Field to check the headspace.

The 'number' you have now is pretty meaningless, as I showed in the link above you can have a 'number' 0 that is bigger than a 'number' 3

I sometimes think, that when reading, some folks only see what they want to see and ignore the 'inconvenient'.
