So this engine shat on me and number 4 piston and head was destroyed. So bored out pistons, ground the crank, new head, among other stuff. well I'm a little slow and had a lot of trouble figuring this timing out. got the new LCE cam gear and I'm not sure which mark to go by. The original one has the notch along with the nipple. Do I have this right or no? The motor is very hard to turn, is this normal?
