I am building a mild 400 for the street car with leftover parts I have laying around. I installed a double roller timing chain I had laying around. I don't remember why I had it on the shelf. Had to be left over from the race car, Well anyway it seems very tight took a little tapping to get it on. Very little slack. After looking up the cat. number, it is .005 undersized. Do you think this would hurt anything or should I just order a new standard one?

Also it's been years since I installed a fuel pump drive on the timing chain. Is it worth filing the flange to get rid of the slop? It is really loose when I tighten the cam bolt.
