Header Gasket Leak - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Is there a certain type of header gasket or tips/tricks to installing gaskets to ensure they don't leak? The P.O had a pair of gaskets each side on my truck and it had always blown a little, so I decided it was time to replace all that with two new gaskets from Mr gasket, and when I first ran it on the new ones it seemed Ok but now it's blowing again particularly on the D.S, I was able to give the bolts an extra tighten so thought that was the problem....but no, it's still blowing.
The fact that my headers had two pair each side is making me think that this maybe some long running problem with my truck, any ideas?
