There is no problem with turning a motor counter-clockwise, except that if you're turning it with the damper retention bolt, you could loosen the bolt and have to re-torque it. There are tools that will fit the crank snout to turn the crank. Next time you go to the drags, watch the fueler and alcohol guys put a bar on the crank and pull the motor backwards a few times. What they're doing is clearing the cylinders of fuel. When you turn the crank backwards, you're opening the exhaust valve before the intake, so you can't compress fuel in the chamber and maybe break a piston or bend a rod.
