Ya the directions that CP pistons come with are very clear and detailed.
And don't just read the part of the directions that tells u which ring goes where and throw it to the side, read the whole thing.
They'll tell u where the front of the piston is, where the ring gabs have to be orientated, ring gap size and all.
You shouldn't even be putting the rings on the piston yet though, first you have to slide them into the cylinder to measure the ring cap.
