There aren't in the exact same spot but they are are from the middle to right before the bend. They are all within an 1/8" of each other and none of them have jumped to the threads instead of the ground strap. I talked to nitro dave some and he said that usually light grey can be a sign of pre detonation but I could have miss understood him. If you have any better info or if anything we are doing is wrong please help because we dont want to blow it up.
