Best 318/x-head /hyd cam combo

As stated those heads might be a little too much for a 318,my buddy runs a "smog" 318 with that comp cam and 1.88/1.60 heads headers manual shift 904 3.91's he's gone 13.75 in a '70 dart..the Mopar cam coming in 2 pieces might be a good omen their cams have never impressed me..
