How big is the header? How long does it take to broadcast *the header*?

You only broadcast that to your miners (if you are a pool) not to everyone else (you do know how this stuff works or don't you?).

And as stated before if you don't validate the txs in a block then you are going to be easily tricked into mining on an invalid fork.

Block 401302: https://blockchain.info/block-index/1085183/000000000000000003ab3fee4bedfd4c8afa723454e322b44b69dd42262ecf9b
This block was mined by Antpool on 2016-03-05 at 17:59:38, it was a "full" block, as you have told me repeatedly it takes longer for big blocks to propagate.

Block 401303: https://blockchain.info/block-index/1085184/000000000000000006910040284ea1769d482a4ab7ea65b30af14aabc2b69749
This block was mined by BW.COM on 2016-03-05 18:00:39, it was an empty block, because the block had not yet propagated to them. They did however, have the header for block 401302.

So, in answer to your question, I don't know exactly how this stuff works, but I know enough.
