Re: Engine Noise
One thing that I have always done on headers with the thin flanges is cut the flange between the first and second, third and fourth cylinders (I.E. for a SBC, between 1&3, 5&7. 2&4, 6&8). Thin flange headers tend to warp after time then it is hard to keep them tight. You can also use the locking header bolts http://www.jegs.com/p/Stage-8/Stage-...49275/10002/-1 .
