After years of interruption,  I am studying internals of bitcoin again,  starting with block header format.  I wanna see in real life,  from blockchainfo info, I can see contents of certain blocks in a web formatted output,  but nowhere seen the block header.
Is there a way to see block header from live public block chain? Any utility?
Following options are fine for me:
1. Using some utility dump header
2. Using some utility fetch (from public chain) entire block including block header write my own parser. Thanks
