I'll be interested to see what you find. I have put about 600km on the bike since replacing the manifolds, no problems so far.I received the manifolds. Will replace in about 500 miles when I do a big overhaul. I've had a misfire in 2nd gear for almost 6K miles. If they simply deteriorate with age/ wear, I'm a candidate.
