Craig, I think the real disadvantage comes when you twin-plug them (which I cant remember whether you have them or not) but what got me away from 3.2's or SC's was when I saw a set of 3.2's crack through the second plug tap to the exhaust valve seat. The machine shop says that the alloy is the last defense against cracks in this area. There is also the idea of going with 12mm plugs and I have now seen someone with 10 mm motorcycle plugs.
