I am considering buying a dura ace double crank on ebay (its only $30!!!) are there any problems using a double crank on a track bike? (chainline etc...)

I have truvativ touros on there now (which have the bosses for other rings) and they are sh*t and the stupid "powerspline" BB is giving out, and is impossible to find (at a halfway decet price) so i need some new cranks and bb and dura ace for 30$ is not bad
