This is out of the Ford 5.4 Lightning Manual Top Ring 0.23-0.49, 2nd ring 0.23-0.49, Oil rings 0.006-0.026 Ford tech book on modular 5.4 Supercharged Just retyping out of a manual. ( Also Piston should be Measured with outside Micrometer and Cylinder should be measured Top middle and bottom with a inside micrometer to determine clearance's then Ring gap can be figured. My 2 cents
