I agree, the entire engine needs to be disassembled and inspected. I would be surprised to see that the cylinder wall is not damaged (in the cylinder that dropped the valve). The block and head should be also magnafluxed, which is a magnetic way to check for cracks. You would probably be better off buying a complete engine kit if there is any wear issues. The reason most shops bore the engine .030 is not to waste time. If there is Cylinder wear, by boring and honing it 30 thousands oversize, you have perfectly round, clean, straight cylinder surfaces. Nothing wrong with cast rings for a stock rebuild, moly coated top rings seal fast and stand up to heat and pressure slightly better, but do cost more.
