The service manual and link I posted both say it should be done with cylinder 2 at TDC. Other than that, that's exactly what I've been doing.

You can remove all the tension from the chain by removing the chain tensioner and then installing each camshaft with no care about angular position or synchrony.
Align the sprockets by the manual, install the chain guard and then the cam chain tensioner.

That's what I did.

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.

It's an old chain, I'll measure how much it's stretched later today. What's a timing degree wheel?
