Just wondering if anyone else has installed the Edelbrock Headers for our vehicles and have this issue...The flange where the headers bolt to the exhaust tubes (I have duals) is mounted is a traingle shape with three bolts to compress the the header and exhaust tube together. Even with lock washers, the bolts have an extreme tendency to loosen and fall out. THis has happened five or six times spread across both sides. I have used lock washers, going to try a castleated nut and cotter pin this time around. Which due to spacing around it might prove to be a giant PTA, but I am pretty sure locktite would just melt away and not do anything to help. Just seeing if anyone else has experienced this. If not, I hope this can help someone who comes along later with this issue...
