The way I set it does include using the timing marks on the new belt.
I do a couple of things that may help. Set the cam to the mark- this is the easy one. The cam likes to snap into place, helped by valve spring tension.
The intermediate shaft is tough to get just right. The mark is indeed almost 90° from vertical, pointing almost straight away from the water pump. I use a small mirror (welding inspection mirror) to get a view of it straight-on. Helps a LOT.
The crank is sometimes tricky. I reinstall the lower cover temporarily, and the harmonic balancer/pulley. Line the crank up to the big vertical line marked "0" on the cover, then remove the cover and pulley.
I also push the tensioner back as far as possible, and tighten it down with the nut. This releases it a little more than just retaining it with a pin or small screwdriver. Gives you the maximum belt slack.
Line up one single belt mark on that intermediate shaft pulley, then the cam up top at the other single mark. The crank SHOULDN'T move while you're sliding it over the bottom sprocket. DOn't slide it onto any sprocket all the way. Start to slip it over the tensioner. Then work your way around to slide the belt fully onto all 3 sprockets and the tensioner. Try to keep as much tension as you practically can on the section of belt between cam and intermediate shaft, to give yourself the most slack on the bottom side of the cam sprocket. Finally when it's all in, release the tensioner. I give it a little push in the "tight" direction before securing the nut.
Now check everything. Use the mirror again to make certain the intermediate shaft didn't move. The cam is easy to see whether it's right or not. REinstall the outer belt washer, the lower cover, and the harmonic balancer. Make sure it all comes out right on! Most often, when I haven't gotten it right, I've found I got the crank off by a tooth. Take your time and double check!
Good luck with it!
