No idea. As you know, when I was having problems with the springs, they said there current spring manufacturer was PAC. But I don't know about MY springs as the heads were manufactured 2 years ago - right about the time they switched spring manufacturers. I haven't talked to them yet about the valves. They didn't call me back.
