I don't have the answer for that question as far as actual experience as this is second hand info from him so I put it out there like that as third party info (but I was very impressed with him) as I was way too busy trying to write down/remember all the excellent tech he was laying on me (for free) to ask specifically but I would assume poor quality/fitment. I'm sure he will tell you & he takes calls on Monday & Tuesday only. John 573 392-7378 I'm assuming inferior quality of some sort & I have seen many gaskets in various brand kits that the holes are slightly off especially cluster gaskets. No overseas brass floats was another caveat he mentioned (poor quality solder that can leak over time iirc).
