I used the 1" SS Stage 8 bolts, 14 per side (two sets). Copper exhaust gaskets . I anealed the gaskets before istalling. The two bolts in the middle of each head are a tight fit. I drilled and wired them. I have alluminum heads and used the 1" long bolts for max thread contact in the head. They don't leak or come lose. It takes several wrenches, and attacks from different angles, and takes several hours. Not something that you casually take apart.
