Ok, I am currently doing a 2JZ-NAT project. I just torqued the head down with arps to 80ft/lbs. I put all of the shim buckets back in from where they came except for 2. These two can be tapped in but will not move freely like the other ones. Also one kind of sticks and will not move up or down. Just to troubleshoot I tried to swap buckets into one that was giving me trouble and they would not fit easily either. Does anyone know what is wrong? I wonder if my head is warped from too much torque on the head? Any help would be great.
