from what i have found out about brushless the kinda rule of thumb is outrunners have more tourque and less for the inrunners

The difference all depends on the electrical specifications, pick the motor that matches closest with what you require, speaking in generalisations an out-runner for low speed applications and an in-runner for high speed or gearbox applications.

The High speed in-runner will have more torque but at an RPM range that is too high.

CAN BRUSHLESS MOTORS BE RUN ON LEADACID BATTERIES

Yes they can, but if they are high current drain the Lead Acid battery wont discharge fast enough without damage.

thinking of useing two 500kv moters in a tug on a 12 volt 20 amp sla battery are these motors high drain

The Drain will depend on the prop, and the speed you spin it at, 6000 RPM a 60 mm prop is going to be about the maximum you would want to use 50 or 55 would be better, if you use a bigger prop, lower voltage or lower Kv motor.

20 Amp SLA battery should have no problem if the above conditions are kept.

The motors can be high drain if the prop is bigger or the voltage is higher :-))
