Extrude Honeing a single plane J manifold

[Joseph~]

Any person who has had a single plane J manifold the ports matched to the gaskets and head, then Extruded Honed?

Howdy
I gasket matched my manifold, no extrude hone.
I installed the manifold and long tube headers at the same time so I don't have a good reference for power increase of one or the other.
The combination is was a great seat-of-the pants increase. Marginally low end but much more in the 1500-2000rpm range.
Next is a cross over tube....just got to figure out where to put it....
Hope this helps...

Wonder if i could add headers to my 6.2 w/ Banks Sidewinder Turbo, anybody done/seen this? Getting a J-intake too.

Headers are absolutely useless with a turbo, from a performance standpoint compared to cast manifolds. The J code intake may be beneficial, though.
