Speed breaks deployment causes a limitations on max .AOA?l mean in BFM.What about on landing configurations? T/O and Landing gains will limit AOA,or speed breaks are "guilty" for this?

Speedbrakes have no AOA limitation.

In landing mode, gear down, the speedbrakes partially close to prevent a ground strike at touchdown.

Normal landing is limited at 11 to 13° AOA to prevent a tailstrike. => (Nozzles, tips of speedbrakes, and horizontal stabs.)

I'm talking about the attitude of the aircraft ,,nose down'' few degees when the speedbrake is released .Speed breaks deployment causes this or is it Takeoff+Landing Gains?

I thought that an airfoil, boards in this case ,it will stall at about 27 degrees angles of incidence no matter the speed

In sim.when i deploy speed brakes of the F16 -A -BLOCK 10 it will nose down 4 degree.Why ?

You would have to ask whomever program the aircraft in the sim to behave that way.
