Re: American exhaust headers

["Mark Price" <mprice@xxxxxxxxxx>]

The 2000 up split manifolds ports are
1 5/16" wide
1 1/8" high
Gasket will allow porting to
1 5/16" high
1 7/16" wide
How this compares to the old ports I don't know.
I don't have any off to look at, nor do I have any gaskets.
The manifolds look like they have plenty of space to allow them to be slid up or down to align with different port heights.
Some day, I'll look into actually ligning one up to a head and see what's what.
