I just replaced my timing chain, guides, oil pump, water pump, and all those gaskets. I plan on changing the oil at 500 miles, re-torquing the head, and exhaust manifold bolts, but is there any other "break-in" procedures just for the timing chain?

I didn't do anything in the block.

 

Do some research on retorqueing some say don't some say do but don't loosen a little and some same loosen then retorque. I don't know where to start but good arguments for all can be found. I probably should have retorque mine after Tchain and head gasket but I didn't. Good luck and let us know what you end up doing.
