#2 looks a lot more like what the factory mark does, (chisel/tool mark), as opposed to the blob that #1 pic has.
IIRC, the correct tick mark will place the protruding magnet on the edge of the flywheel at somewhere around 2 o'clock when looked at from the rear.
If you're at TDC compression and the magnet is anywhere but in that region, then it's wrong. For example, if you used the wrong mark (there really is only one, and again, it's a tool mark not a paint mark, though the tool mark may have been painted for clarity), it would end up at around 7 o'clock which would throw out the timing by 180 degrees.
I 'think' someone had posted a photo of exactly how it was on thier car showing the mark and magnet orientation quite clearly. (Eric?)

So, was the flywheel installed wrong? As Tifosi says, the factory mark is seen in your picture #2 - the one without the blob of white paint.

Pull the cam cover check the cam lobes to make sure they are pointing outward on #1
I think that you are 180 off, But will the the flywheel actually fit 180 off? I'm not sure.
With the Ljet unless you have modified the distributor it is impossible to alter the position. However If you pulled the Oil pump and moved the gear and stem up to the distributor out of position, then you could alter the distributor position. But I don't think you did that. I think the flywheel mark is suppose to be where your white mark is, but only if the cam lobes are pointing outward
on # 1.

I put a zip tie in number 1 to see when the actual cylinder hits TDC, but i'll check with the cams, but i never messed with the oil pump and I've never messed with the distributor. So i'll see where the cams are take a pic of them at TDC and we'll se what happens.

Also take a picture of the distributor (cap off) with #1 at TDC/compression.

so the lobes are pointing out and the dizzy is at the correct position. I'm beginning to think that the white mark was for mecahnic who last replaced the clutch. He may have made a mark 180 so that when he was under the car he could "see" where the actual mark was by knowing that his white mark was 180 out. I spent my two days off swapping out my interior so didn't really get into the mechanical work but more pics and hopefully a running car will be next on my agenda.

May be something, may be nothing
Prolly not related to your issue, but something I spotted and felt the need to ask about:
Are you at exact TDC when those pictures were taken?
Do you have different than stock grind cams?
Did you alter your exhaust cam timing toward more advance at some point?
The only reason I ask is because if they are stock cams and you are at TDC, and didn't advance them for some alterior motive, then the index seems to be a quite a bit off. (granted, one can degree them with a wheel and have the tick marks not quite line up, but wow, that's a lot of degrees in that picture)

OK. I've got a startup issue as well. I pulled my water pump, (Yes I pulled the crank pully, with a torque wrench -- came right off) but now I have everything assembled and the darn thig won't fire up. It'll turn over, but it doesn't catch.
I looked at the coil and it seems like the neg is getting spark, but nothing on the pos side. Is there something that I could have missed or misaligned?
Help.

MAF sensor plugged in, or is this something that cropped up before getting the airbox reinstalled?

Big silver thing with a square black plasic cover in the middle that mounts on top of the box where the air filter goes.
Has big bore hose going over the top of the engine connected to it and a wiring harness plug from the left/drivers side fender.
