Need to get a timing degree wheel.
If the timing chain is old it looks like the chain is stretched. if you line up off the exh the int will be out and the opposite the other way. this is where adjustable cam timing int and exh will come in handy.
If its a new timing chain degree off the int side. Rotate the internals from tdc two or three times from the crankshaft and see what degree timing is out after that. Then adjust the valve clearance after that.
