You will have issues getting the intake mating up with heads with that much milling. Each .007 will take you down about 1cc so that is a lot material on a 66cc head not to mention the PTV issues it will prolly bring...
243's are 64cc and will work much better.....
edit:The 862 heads are stock 5.3 heads and are 62cc heads so not much milling to get them down to 60cc. They have smaller valves than the LS1 castings but are not needed if the are going on a 5.3 motor.....
