See how it is closer to the rear of the hole, it fits alot better if you trim the hole. Not a big deal at all, took 5 minutes.
Thats just the nature of off the self kits. Its hard to make everything 100% when using a jig to make the kits. Glad to see it was an easy fix. You may want to line that sharp edge with something incase the movment of the engine makes it rub.
