Does it run ok - any weird noises? There is a 'tight spot' on them when you hit the compression at the top of the stroke which is what this looks like. What did it run like before you put the new head kit on? Did you put new bearings etc in when you did the head kit?

I have a ddm 26.9 head on the new engine I bought so will be interesting to hear what they say

did you line up the piston ring when you put it together. looks like it has caught the port on the way up

I don't need to tell you that if you're rebuilding an engine that has had bits come off the piston like yours, then you'll need new bearings and seals because you know you'll not get all the swarf out no matter what you do.
