Need timing marks for proper chain replacement

u need a repair manual-find one at fixya or go to library and look in the chilton books
SOURCE: Timing marks? Installing timing chain
crank TDC ,cam ?? look on the back of it for a slot if a slot then it should be horizontal with the head ,dont know where the mark is on this vehicle ,didnt you put white paint on it first ?? i can tell you how to do it without timing marks if you cant find the marks
SOURCE: top end cam and crank chains are off!
I can help you with this.You have to start all over again.There should be three chains all together. Two short ones and one long one.The two short ones are for the cams. We are going to start with those two first.The 90 degrees they are talking about the timing mark on the gears on the cams should be 90 degrees from the flat surface of the cylinder head.The easiest way to do is find the marks on the gears and then find the links on the chains that are different color line those up with the timing marks on the gears. There should be 12 links one color link to the other. Set those and put the tensioners on little tricky on those. When you are going to set the big chain the cams are going to move some don't worry about as long as those color links stay on the timing marks. They will move a little and it looks like they are off but they are not. Once you do that the long chain also has different color links also align those with the timing marks on the cam sprokets and crank gear.Install your tensioner for the long chain. You have to collapse the tensioner all the way in and install collapse. Once in with a screw driver pry in against the tensioner to realease it. If you fail to do this you will hear chain hitting the metal cover when you start it. Once you have this together you can turn the engine in the direction that it normally runs manually and it shouldbe free. Keep in mind that once you turn the engine you will never get those timing marks to align the way they were it still ok. Hopefully this will help. I have built a lot of these engines for my customers.

found this, and from what I could find it is a non-interference engine:

Timing the Cam to the Crank
There are several ways to time the cam to the crank. Be sure to check the manual before you install the timing chain or belt.
If the old parts are available, carefully compare the new gears or sprockets with the old ones. Check the keyway and timing marks just in case there might have been an error made in manufacturing. Sprockets are sometimes stamped backward. Its much better to find the problem during assembly, rather than waiting until problems show up after reassembly and reinstallation.
Maintaining Valve Timing
During a valve job, it is essential to keep the timing chain or belt in place to maintain correct valve timing. Position the number one cylinder at TDC. Some overhead cam engines use a single long chain for a cam drive. The chain can be wedged against its guides with a tapered block of wood.
the chain tensioner on some ohc engines must be wedged to keep the chain in position during cylinder head removal. courtesy of nissan motors.
Some engines have a lower and upper chain. These engines do not require special attention to wedging the chain. Be sure to look for hidden head bolts and check the repair manual before removing the OHC head.
