Ok I've been reading past forums and need clarification

TDC? On the balancer there is a clear red line, this lines up with the timing marks on the block, there are 3 there which is TDC.

also does the crank rotate 2 full times where the line could come in alignment with the timing marks making the timing 180 degrees off?

Does this mean not only do you have to verify the mark but you need to take the spark plug out of cylinder 1 to confirm that piston is at the top?

And also to confirm when that happens the rotor should be pointing at that plug #1 then following the firing order as marked on the intake in counter clockwise pattern
