Help me set my timing back to TDC! HELP!!

So I am working on replacing my head gasket and doing a mpfi swap at the same time.
I have a 91dx with d15b motor.
I had the head set at tdc but accidentally moved the crank after I had removed the head.
So with that said do I just set the crank to tdc on the marking there?
Then set the head and cam to tdc and install everything from there?
I want to make sure I do not F anything up when re assembling things and do not somehow set it to be 180 degrees off.
This is my first time doing something this detailed and would like things to run properly once I am done.
I downloaded a service manual but want to be sure what I am looking and and reading is correct info.
Any help or advice is greatly appreciated!!

Looks like mine has a white dot on the top of it which lines up with a groove on the bottom cover is this an actual marking or something someone put on there?
it seams to be pretty darn close to TDC from what I can tell but not 100% sure.
I really don't want to take off the crank bolt if I don't have to.
Put the head back on today and everything seams to be ok, I have only spun the motor by hand at moment so want to make sure before I start it and have issues.
BTW I went to middle school in Marietta, Mcklesky was the name of the school.
The white mark does not line up with the tooth coming off the lower timing belt cover.
It is about 1" or so towards the exhaust side of the block. It lines up with the side of the grooves for the tensioner. I had a long piece of tubing inside the spark plug hole to make sure.
I checked twice and same result.
Any idea why it's not lined up with the tooth or is there another mark I'm suppose to line up with.
The pulley is the one with the holes in it.
Don't want to start it when the time comes and screw this up!
Try this and see if this will help.
its pretty easy and seems harder than it really is trust me once its timed right just crank the pully around acouple times so the tension is compensated.
hope it helps
If I line it up with the tooth on the lower cover the #1 piston is not all the way up yet.
It's a bit off then if turn it a little more then it kinda clicks and I can feel it going nto place and the dot is about 1 inch towards the exhaust side of the tooth on the lower cover.
From what I have seen in pics online the marks are a line mine is a white dot not sure if I am looking at the correct marking?
Seams maybe not.
I will take another look today when I get home and snap some pics to post up.
I got the crank set finally after sorting through things and thanks to everyone and google for pics I found the notches to line things up. Knew i had to be missing something, had to remove the alternator belt and there were the illusive marks. I had it very very close if not correct but now the line is matched up with the notch on the crank cover and I can finish up everything else to try and get the wagon to come to life again soon!
I Don't think anyone mentioned it specifically, and it's easy to miss in the pics, but there should be a total of FOUR marks on the crank pulley. ONE mark is all by itself, that's the TDC mark. It SHOULD be white, but usually the paint has been worn off or smudged with dirt/oil. About 16 degrees over, THREE marks are all huddled next to each other. These are the marks used for ignition timing. I believe they represent 14, 16, and 18 degrees Before TDC. The center mark is usually red, and I can't remember if the other two are white or unpainted.
On all my cars, i usually can't see any color on any of the marks, so I always paint the TDC mark AND the three timing marks white so I can see them easily with a timing light. I'm sure other people do the same thing, and there's always the chance it's been done on your car. Just so you don't mix them up, make sure you always locate ALL of the marks and pick the right one.
I am curious, you ever get it all back together and running?
With everything set at tdc the timing is retarded by about 1/2" even with the dizzy fully advanced.
I have it set 1 tooth forward and will be adjusting things 1 more time tomorrow to see if all goes well.
If I have it retarded the motor wants to pop at times but drives ok.
Seams to want to smoke for some reason when I had it set with the cam advanced so I'm trying 1 last time to see if I can get it with 1 tooth advanced and not have any smoking.
It's the weirdest thing can't get it times with everything set the way it's suppose to be.
B7 head and pretty sure cam gear and cam as well.
Might need to get an adjustable cam gear for whatever reason.
Fighting issues is no fun thats for sure!
The orange wire from C1 should be moved to B10
The White wire from C2 should be moved to B12
I have read that getting these backwards will cause your timing to be severely retarded.
