			Sorry about thank Jake,  guess it was a little long winded. Here's the simplified version of the same question. 
 
The head has been bored out to fit a 103mm cylinder. 
 
The chamber in the head was never cut out bigger. 
 
Question: Can a cylinder of stock dia. with a spacer be put back into this hole.
