Yes, he was talking about Hondas, Toyotas, and Mitsubishis, possibly some 
modern small GM engines, too. I understand that multiple valves per cylinder 
make for lighter valves, but I hadn't thought about the fact that these cars no 
longer have pushrods, and most of them don't have rockers.

If the cam is milder, that makes a BIG difference. I was not aware of that, 
and it probably makes up the difference in my understanding.
