sorry to hear she is knocking! how high are you spinning her up? changed the oil regularly I am assuming. Not sure what the mileage is but its highly unlikely the crank or the bearings are an issue if its a young bird.
more than likely you should be able to pull the valvecovers and check the rockers, and pushrods. if all seems well there, go to the lifters, and check for pits. If they are pitted change them and also the cam. these are the most common ticking noise issues. good luck.
