degreeing their cams. If you ever installed factory or stock cam gears, there is a lot of slop in the timing marks. One degree on the cam is two crank shaft degrees. Also when you machine heads and block surface, different thickness gasket, the timing will be affected. Because we have a V engine, the cylinder banks can be out of sync with each other with regards to cam timing. Most here just put it together and trust it will be right. This will work fine for average street car. I don't consider our engines average. A HP engine requires precision timing. To do it right you need to degree all 4 cams to make sure they are in time with specs. Of course this my opinion. For your reference Timz posted how he checked cam at factory setting and found the timing all over the place.
