Ya and a liquid cooled one at that, which is why I put an old XT topend on it, no room for the radiators(or really a need for it). It is 101mm high comp Raptor piston and sleeve though rather than the 95mm XT. My one worry is the piston tapping one of the intake valves at higher rpms, I confirmed it doesn't at just above idle, but do to no head oiling at the time I couldn't rev it or run it for long before tearing apart to see how things were living. (I was hand pumping oil into the end of the cam as it was running.
