Dave,
A very experienced machinist could indeed do this with some reshaping of the chambers, yes. However, ive seen a few done over the years and they tend to be a bit poor IMO with some valve seat failures recorded after havng it done. Thankfully none of my customers.
Deffo a discussion i must have with Karl though if i can ever get hold of him
