Default Timing belt question

I struggled with the timing belt for a good hour or two and this was the best i got. Crank is tdc and the left cam is aswell. The right cam as you can see here is about half a tooth off. I've heard that thats fine but i wanted second opinions. I didn't pull the pin so i can readjust if i need to. Thank you!

Ive seen this video. I did it exactly how he did it. I dont have those timing marks on my belt. I'm asking for opinions on if this is an acceptable amount of "gap" on the timing marks. What do you think just based on the picture. Also to clarify the other cam and crank are PERFECT this right cam is maybe a quarter tooth off. I've heard on other videos and post that its ok to have the right cam (the cam with no outer lip so the belt slides on easier) be off by just a tiny amount like shown in the picture.

There is no picture. edit - I see it after a forced refresh. Why are you using an old timing belt? Without a belt with marks you can't be sure the belt is 100% correct.

I'm swapping a 94 1uz into my 93 sc4 after blowing it. I bought a bunch of parts but didnt think to get a new timing belt.. ik dumb mistake but i also know that this belt only has 3k on it MAX so I dont want to wait a week for a new belt. I've done this job without the marks on the belt before and it ended fine. I just got annoyed with trying to get the cam mark absolutely perfect and figured i'd ask for an opinion. Also i see alot of people disregard the timing marks on the belt as they prefer using the marks on those cam timing plate covers and the tiny dots on the crank.

That belt has way more than 3K miles the lettering if half wiped. BTW you can't judge the mark alignment before the tensioner is active. If it was my engine I would not risk damage because I was in a hurry but your call.
