Stage 8 Pro Team Member of the Week is Jim Quirke from Painesville, Ohio. He had to replace the engine in his “Big Red” ‘05 Chevy 2500HD. He decided to put on headers, and the bolts loosened up within the first week, then again after re-torquing them. A couple of his buddies with muscle cars suggested Stage 8, and it was the best thing he could have done to keep the bolts in. They were easy to install and are still holding tight after 2,000 miles on his daily driver. Thanks Jimbo!
