Thanks Mark H.
i always try to make the Runners same Width and Height...but some times you can't unless you start welding
that Manifold only had the ditch or big indention welded up between the Port Pair Runners
it did not have as much welding as that 1st black colored Manifold that made 815.8 Peak HP at 8200
that manifold made :
Peak HP = 808.4 at 8100 RPM
