Degreeing Cam Needed???

hi, it's not so much the cam is off, but the gears can be and are indexed wrong. If they are off, then cam will not be installed correctly. I have seen this before. motor has no power, etc. I have seen a cam gear off as much as 13 degrees. I wouldn't trust the gears being correct. it is better to check it now, once in car, way more work, expense.
