are there any good headers out there for trucks? I've got mine running finally but there is a bad exhaust leak at the manifold. since I have to replace the exhaust I figured I might as well put on some headers and a nice muffler.

also what are the symptoms of a cracked intake manifold? I was told mine is cracked but can't physically see any cracks anywhere.

Thanks for any help you guys can be!

Poor running, low intake manifold vacuum, poor fuel economy.

Go for the Dutras, cheaper than headers, last longer, and are much easier to live with on the street.

where is the best place to find dutra duels? I am looking on line and haven't been able to find much on them.

what is the ideal manifold vacuum level? and where do i test it? I don't have anything to go off of as far as fuel economy, the truck hasn't been driven more than a couple of miles in the last 8 years (I bought it after it sat that long and have put the few miles on it in the last couple of months)

There is a new set of truck headers for sale on moparts in the other mopar engine section.

You can contact Mr. Dutra here on this board. He posts as "Doc" or "Doctor Dodge."

Ideal intake manifold vacuum depends on many things. On a stock slant six in a good state of tune you should see 18-21 inches of vacuum.
