No but I've helped a buddy do his. Not complicated if you follow the instructions. Most important is having the engine at piston one TDC on compression stroke before taking anything apart.

And take plenty of pictures, in a pinch they sometimes can help out.

Take your time you'll do good. No short cuts to do this. Did you get a new tensioner?
