6.0L timming marks, help
I have a 2009 gmc van with the 6.0l engine, it broke the cam gear alignment pin and spun the gear. I have replaced the bent vales and have new timming chain and gears but I don't know which mark on the cam gear is the timming mark. any help thanks

Here's a picture. Notice the notch at the bottom on the cam gear and there's a notch at the top on the crankshaft gear. Make sure piston 1 is at TDC before you install. The crank key usually points toward 1 when at TDC.
