Hello, I am placing new pistons and Rings into my 2001 escort 2.0 single over head cam. I bought NPR rings and pistons. I decided to check the ring gap on the rings. The upper I am getting 0.08 inches to 0.09 inches and the lower is 0.27 inches. The book states 0.10 to 0.30 is ok. My question is the upper ring gap close enough to go with it? The motor is all standard parts. Thanksfor your help
