You say you just had this work done? I would be taking it back and asking the garage to sort it out.

LTFT want to be in the range -10% to +10% and preferably as close to 0 as possible.....

I changed injector seals, inlet manifold gasket seems to get worse as engine gets hot

Check all the hoses for the inlet are fitted correctly and not leaking... If you can't find anything obvious then I think you better take it back and ask them to check the timing, If they put the new belt on one tooth out then that could cause your issue....
