Taking chain apart and its affect on strength and reliability
My chain, Dura Ace 7800, is a little to short. Would it negatively affect the overall reliability of the chain to add the extra links I need? Or would it be better just to leave it the way it is? I do not absolutely need any more links the only gears I cannot go to are gears I should never be using anyway, 53-27 and 53-25.
As for piece of mind I wouldn't mind having the chain the proper length. Thanks for any help you can offer.

Add the links, but use the special pin for that purpose. Too easy to mess up sometime while climbing a hill and doing some serious damage to your bike, or even causing a crash by inadvertently shifting into one of those 'forbidden' gears.

+1 on adding the links. Murphy's Law dictates that you will shift into one of the "forbidden" gears; the damage/injury will have happened before you know what hit you.

I'd add the links but use chain breaker and do it with the rivets. Just be careful when you press it in that you don't bend the side plate or push the rivet to far on either side.

As long as you use the Shimano made closing pin, your chain with 2 splices will be as strong as it would be with only one.

But if you prefer, you can close the chain with a connecting link from KMC or others. these are also readily available. With the pin or link, be sure to get one that matches your chain's width.

I've had great luck with the KMC powerlinks. after being stranded 40 miles from home once, I now carry a chain tool and a KMC powerlink on every long ride.
