After installing the latest Clover (v3330), when your use the bootpack, only replace ACPI and Kexts folder and the Config.plist file. Nothing else should replaced, otherwise you'll revert to the version that's from the bootpack. Just have to make sure drivers64UEFI has HFSPlus.efi in it. You could replace themes too if you have your own themes.
