How tight is too tight. 512 stroker rebuild

We are rebuilding a 440 to 512. New crank, of course, cam, pistons, heads, rods , the whole ball of wax as they say. During the assembly we would constantly check the rotating assemble for binding and tightness. all seemed to be good. We assembled the heads and adjusted the valves. Finally we checked the oil flow through the heads before closing up the top end. The engine has sat for 4 months while I procrastinated doing the 727 rebuild. When I went to turn it over by the crank bolt with a breaker bar, it felt tighter than before. I did not reprime the oil before doing that but I will before starting for the first time. How tight is too tight? Any guidelines for how much torque it takes to turn it over? I am finally getting back into this after a break and my memory may not be the sharpest.
