Does it matter if you use the #1 or the #4 piston when setting the cam timing using the intake lobe centerline. Say for the cam, the intake lobe centerline is 110 degrees, can you set the #4 piston to top dead center, zero the degree wheel....and use the #4 piston intake lobe to check the centerline?

Some degree the four corners. This will tell you if your crank index and cam are spot on or not. I degreed #1 intake first and then checked a couple other holes (in and ex) because I was curious.
