To clarify I assume when you say "no header at all" you mean the engine was tested w/its stock exhaust manifold? The only other meaning would be the car had no exhaust manifold at all, esentially running the cylinder head "open" which makes no sense.
A header w/a good design should make some gains on our cars, when I say good design that doesnt mean the 4 into 1 DC header that recently came out. 4 into 1's are for higher (5000+ rpm) applications which means on the lower end your dead...unless of course you drive around at or near redline all day. Do some research, DC's own website highlights this fact!
Just trying to help out the inexperienced. Peace.....

no i meant no header/manifold at all. just open exhaust out of the head.
i'll try to find the mag. around the apartment somewhere but not sure if it will still be around, since its an old mag.
and yes they did make more whp/tq with nothing connected to the head... i'm not a designer/engineer so i'm not sure as to how/why but it did...
