Since you can restore and rejailbreak its not too bad, but for the most part, Siri ports are a mess. They may work at first but at some pint you'll have issues. They alter system files so when you remove the port, it leaves a mess behind because they don't really fix the files.
Sorry I don't know what to recommend. I've never used them personally. I've just read a lot about them. Maybe you can find a safe and reliable package. Good luck!
Edit: while viewing the main jailbreak and hacks sub-forum, search "Siri port" with the "Search This Forum" tool drop down underneath the forum page numbers in the top right. You'll find a TON of threads on this topic.
