I recently pulled a set of cams out of a 65 XLCH. The #1,#3, and #4 cams were P cams, but the #2 cam was an XL. I've been told that this was a stock setup for 1965. Something the factory did to make them easier to start. I'm wondering if anyone can confirm, or deny this as a factory setup. I've searched this site, as well as online, and I can't find any info on early Ironhead cams.
