Re: gasket question

you might possibly find a copper hasket for your application, or a thicker fiber gasket, possibly even 2 stacked together?

headers are a pain to seal off, especially if there isnt a solid strip of metal that runs the full length, if its a small square on teh end of eack single tube itll be tough!

always liberally coat the bolts with antisieze

Re: gasket question

I always put a straight edge against the gasket surface of a new header ( 2 foot carpenter level will work ) you would be amazed at the poor fit of even expensive name brand headers. I true them up on a belt sander, sometimes you need to add some weld in the low spots. A little bit of extra time now will save you a lot of frustration in the future. I prefer to use the aluminum covered stock style gaskets, they last a long time, but will not seal poor fitting headers, so you have to make sure the header fits good.
good luck, jjc
