I don't use the sequence but it can't hurt. I do not use the alternator mark, I never take that cover off. I have heard of people getting it wrong that way but I never have.I just make sure not to move the engine once I start disassembly until it is fully re-assembled. If you get it wrong you will bend valves.

I learned all I need to know about life by killing smart people and eating their brains.
Eat right ,Exercise ,Stay fit, Die Anyway!
