Currently working on #0446's engine. When I bought the car, it came with a second set of cams. They were stored in Crane boxes and the lobes had a much more acute angle to them. The ones installed in the car were much less aggressive. I was wondering which set of cams are the originals, why they might have been changed out, and which would be better to use (for performance)?

(NOTE: "Current" = cams that were installed in car, "Came with car" = second set of cams that came in Crane boxes)
