Ring gap depends on a number of factors including but not limited to : Finish bore size, piston type, boosted or non and machining method used. You better make sure you know what it should be at for your app or you will end up with a lot of damage as JET mentioned. Building your first motor is many times an expensive learning experience, hope it goes well for you.

Another thing you should really consider is that the ring seal is a huge factor in performance, if you go wide and safe on them, you are losing power through them, so it is a balance to get it right and you should spend the time to understand how far to gap them and why.
