Hello MoonDog 65Blur is wright 882 Heads make good heads for a grocery getter you could spend money on 2.02 &1.600 valves but that is like puting a 1050 cfm carb on a 350 motor you just can't get the air down the 170-180 cc intake runners even with massive port work you might get 190cc runners befor you run into push rod hole the best thing going is the vortex heads for factory but if it were me I would go with a set of Iron Eagle or Dart in the 200cc runner that would put you in the 4500-6000 breathing range or the 215cc up to 7000 on a 350" with not to mutch loss on the bottom end.
