I started by removing the worn-out heads, cam, pistons, rods, and crank and inspected the bore for major damage that could not be repaired by the honing process. Look for cracks and coolant along the sides of the block as this may be a sign of stress cracks in the block that will leak coolant. Also, measure the bore to see if oversized pistons have been installed. If you have .040-or-bigger pistons already in the block I suggest looking at another block; if anything happens you might not be able to save it. It was obvious that this motor was in need of repair—to add insult to injury, the head had burned valves.
