If i broke those valve guides would it not be obvious to me that i did that?

One thing i did not do right is to have a cam lob at exactly 1 o'clock position in many instances. I followed the manual from Kent Bergsma (mercedes source) who recommended to use starter (turn on ignition key for a short time) to move the shaft. This way is hard to have cam lobe aligned perfectly the way it should. So my suspicion is that my clearances are really much bigger than they should because of it. Does this make sense? Would the car behave this way on the much bigger clearances than spec?
