The confirmed bad batch I was referring to were 288/280's for the S54B32. Keyways were F---cked. $2000 paperweights. Will not be noticed until startup, unfortunately.
During the post cam debacle investigation... it was mentioned that many other cams/keyways for the S65 and S85 were made similarly. No known issues at the time...
SYT_Shadow may have found the first case in his hometown for the S65 cams.
You can measure the cam deviance with ISTA and DIS. It will be readily apparent especially knowing the mechanical timing is spot on....
