are just reference from the OEM. If you degree the cams using a timing wheel as should any HP engine builder should do then timing marks on the timing cover are irrelevent. The cam gears need to have enough adjustment range to be off one tooth. On V engine , timing is more critical because you can have one bank out of time with the other bank. You get imbalance in the power out put per cycle.
