Speedmaster 21 header question

[Wayne Johnstone]

On a recent for sale post re a 21 speedmaster mono, a question was raised re what header to use for a novarossi 21dd in this boat, a comment was made to use an offset hydro header. My question is what exactly is an offset hydro header, is it just a higher degree header or something different?

I believe they referred to the 40040 cranked manifold

Has anyone tun this header? Any performance drop due to the bend?

Yes I have tested them all... No performance difference!
