Brian, I will be replacing the chain soon too (probably late July), but the tensioner pin and tensioner rail need immediate attention. (I wish I would've taken a picture while I was doing the valve adjustments.)
Are you sure the tensioning rail needs to be replaced? The surface of that rail is made out of unobtainium and it's almost impossible to wear through it to the steel backing material.

My 617 had a groove in the rail that was maybe 1/3 of the total depth of the material. I'm sure the rail is good for 400K miles.

Before you do all that work, take a couple of closeup photos and post them so we can comment.
