Cam install
Just make sure you use the right dots. I bought a timing set with multiple key ways and used the zero option as the dot and had my cam about 45 degrees off. Made a mess of my intake valves.
My point is, a degree wheel would have caught my mistake, and there were some that said that is exactly why they do it. Never know when something was manufactured wrong. In the end, it was my own mistake to which I did fess up to. But my mistake or someone's manufacturing mistake, either way, a degree wheel would have saved the day.
