THANK YOU ALL
Thanks to your advice i found the source of my problem with deadlift and the way to fix it.
I have super tight and WEAK hamstrings, what surprised me at first, because I can do 440lbs full squat(or 360lbsx10). So I did not think I could have that WEAK hamstrings! By the way I solved another mystery - why i can squat 440lbs but cant pull more than 390lbs.
Now I pull my main sets from 3inch blocks, but instead of increasing weight I had to drastically reduce it because with proper deadlift technique and bigger weights i felt tremendous load in my weak hamstrings (my legs shake like crazy)
For supplemental work i choose RDL
And besides this I'm trying to master hip hinge, and i do few mobility drills.
Over time i will remove blocks inch by inch.
Get rid of this imbalance will take some time but I'm not in a hurry, i want do it right
