It depends on what your goal is. I use both types, but I use the clamp on gas blocks for the rifles I want peak accuracy. For a hunting rig the set screw should be adequate. You will have to decide which one is best for your set up. Clamp on gas blocks require a bigger hand guard I.D. compared to the set screw type. If you decide to use the screw type, I would only lightly dimple the barrel directly under the gas port and tighten both screws to the 20 inch pounds as I suggested before. You can use Red loctite or Rocksett for a thread locker. Rocksett resits heat better, but is harder to break if the need to remove the gas block occurs. Two barrel dimples are not necessary to prevent gas block slippage. If possible, I would use a jig made for dimpling and use a bore scope to verify the gas block port is not clocked from the barrel port before dimpling. SLR makes a good jig for this process. They can be purchased for the proper barrel journal size.https://slrrifleworks.com/750-dimpling-jig/
