Probably not. When in doubt, take a look at the block explorer: http://espv2.miningalts.com
It is a good source. Currently showing last block is 656095, mined two minutes ago.
While i typed this post my block number at 659378 and i saw http://espv2.miningalts.com block number at 656340.
So i decided to remove old chain and syncronize with new chain and i add some node that used 0.8.5.4, same as my wallet version (0.8.5.4-patch6).
Is this will make my chain correct?
Supposedly yes. Did you check if your IP appears in the list of nodes when your wallet is up and running?
