Gallery Gasket Questions

south

Alright so im attempting to do my gallery gasket soon and im getting a whole list of new parts to swap out, oem and aftermarket. If you guys have any recommendations do feel free to let me know ill list them down below. Now my question is im going to be buying a new primary chain since it’s coming off anyways and I want to swap out the water pump too since i am already in there. Now the new oem primary timing chain does not come with the colored markings (Z1 has told me when i asked) Now how am I supposed to put the motor back into time if it doesn’t have any of the colored markings? Do the colored markings matter with a new chain? Or does the chain have dimples in it to make sure you can time it out? Im at 93k at the moment thats why i figured id swap it out. Also before i take the tension off of the chain is there anything else that I should do? Should i put the motor in tdc? If so how would I do that? Is it just cranking the motor by hand and checking cylinder #1 until its at the top?
