Attached a bunch of pics. Sorry for the delay, I couldn't find an extended T27 torx bit required to remove the head until now.
Oddly enough I had a 30cc piston and 4 bolt head laying around and decided for fun to see if I could bolt it onto the 2 bolt 29cc bottom end. It fit perfectly fine and the piston moves smoothly with lots of compression. I used the 2 bolt gasket and it seals just fine. Any reason why this wouldn't work? I wasn't able to find any info on people attempting this.
BTW, as for the condition of the damaged piston and head, I noticed the spring clip on one side of the piston was missing. Do you think maybe it flew off and caused all that damage? It honestly does't look like a lean condition failure. It literally looks like a foreign object got grinded up in there. Anyways, opinions please? I'm not engine expert.
Yea ,that would do it ,I had a rod bearing grenade one time an did that!
I think in some engine displacements ,some of the blocks are actually the same size ,if they are a close to the
displacement ,like a 23cc & a 26cc ,but ,jumping up to past 30cc an higher ,the blocks change ,I had seen some
parts where you can change to a bigger head an piston ,like a bore up kit!
