That feel is the bolt/stud stretching. Tighten as normal, apply pressure until you feel a slight give, STOP. That is how tight it should be. The other answer is, how tight was it when you took it apart? Make it about that tight when you put it back. One exception is spark plugs, I always angle torque them to about 90 degrees .
