Steering having a kind of squeeling noise when i turn the steering wheel?

The bolt heads stretch as you tighten them. Like a spring or rubber band. If you stretch the bolts (elongation) they are overstressed and the extra stress the running motor puts on them might stretch them enough to break them or cause head gasket failure. Stripping, head distortion and block distortion are also considerations. If tightening them harder was a good idea the specs would tell you that.
