any one recognise this work....
Has got o ring conversion but measuring 63mm ID.
also has had work to head area....looks like it has also been skimmed the cylinder head area is nearly flush to the rest of the head..
will this have been done to work with different pistons ?

Interesting - it looks like they are for flat top pistons and looking at the chamber volume some serious fuel.
That is also one huge squish band.

Difficult to say from the piccy so might be wrong. If they are flat top they wont work with stock pistons.

few more piks...
