I usually do set mine up a little on the tight side, but do adhere to factory specs. I just like them to run a little quieter. There is a sheet for the adjustment procedure complete with instructions and pics in the CD rom. We carry them in the partsshop. I suggest you get it if you haven't done this before. (Both cams have to be taken out and re-torqued in)
