340 break in question

Also.......If this was a roller motor non of this would matter at all....my last roller motor I fired up, set timing, drove to the gas station 1 mile down the road to seat the rings (pulling up on second gear to 3500RPM and letting the car slow on its own, over and over for 1 mile), checked for leaks (it was warmed up by then), turned around and floored it home, shifting at 6500. That motor ran mid 10's for many years, no issues.
