You need to bring #1 up on TDC and get the pointer alligned with 0 on the balancer. Then be sure the chain is tight and align the left cam on the assembly marks and get the chain on the left sprocket. Then remove the right sprocket, and pull the chain tight and you should be able to slip the sprocket into the chain and put it on the cam with the cam positioned very close to the assembly marks. Then put the tensioner in.

Rotate at least once by hand and verify, then crank it with the starter, which should fill the tensioner and tighten the chain. With a new chain you should have both cams lined up with the timing at 0.

Would not start the engine until you get this sorted out.
