Stay away from the Procomp bolts!!! I bought several sets of head bolts and main bolts and had nothing but trouble from them after installation. First off the thread pitch is not correct and they will leak coolant like no other, you will need lots of silicone to get them to seal. The next thing that will happen after getting them to seal up is they will break after you TQ them down 3 times. The bolts have been hardend to too high of a rockwell hardness and they are brittle.
