Thanks... What if my end gap is .014.... ??

Also where should I measure the end gap? Top ,middle or bottom of cylinder?

If it is less than .016 you use a file and widen it a little bit.

If the end gap is different top, middle, bottom then your cylinder is tappered and you need to have it fixed.

I usually take the ring and insert it in the cylinder from the bottom. Use the piston to evenly push it up to just below the exhaust port, then measure the end gap.
