Or a ball hone will work nice to. They radius the ports at the same time you hone the cylinder. As far as the "pivot idler arm" just take the 2 bolts out and jam a wedge in the slot to open it up a little. A straight screwdriver will work. It looks like you already have it marked. There should be factory marks on there already but it doesn't hurt to mark it yourself to make sure it goes back on the same way.
