Inside and out, within reason. You're going to find sharp edges around the machined surfaces. Pay attention to the main caps and the saddles they sit on. I even deburr the drilled and tapped holes for the main bolts.

Also there's a **** ton of casting flash in the lifter galley. I grinded that all down smooth and also I smoothed out the oil drain paths in the lifter galley. Just be careful not to slip and hit the bores with whatever sharp tool u use to grind or de burr.
