Nick, i’m glad you posted here. I was looking for your other post you mentioned to ad to this thread. it’s one of the main reason these problems exist in flat tap at cams. Deviating from the cam core shape when changing centerlines and lobe shapes making hardness treatment very thin in some areas.
If you can find that post it’s worth reposting here. It’s very insightful and worth reading. thanks, Rob.
