As I posted,I suggest he goes with a BBC.
I appreciate you being civil about the ring issue, but all of the data collected by all of the major car manufacturers shows that you're wrong. They're switching to thinner rings for a reason- more power, better sealing, less bore wear, and as a result better emissions. Many of them are also switching to steel rings (a lot of foreign cars have used steel rings for decades).
The singular advantage thicker rings have is cost. for sbc's a cast iron 5/64ths ring set is still the cheapest set by a LONG shot.
