I've got an Autolinea twin port cylinder head for sale. There's less than 1000 miles on it from new but its got a dicky plug thread on one cylinder. The plug will tighten up to the specified torque but it feels rough on the way in and the threads look a bit dodgy.
Comes with valves but no springs, collets or retainers (I've nicked them for another head)
€75 euro
