Clifford Performance has finally produced a run of Hudson 6 headers.
I bought a set yesterday for my coupe project-photo attached--he says he has 4 left.

25% increase in power and torque claimed.
Is that accurate? Quite a boost for the money.

I'd guess 12% increase at the rear wheels
and an additional 13% between the ears,
because it sounds so good!!
Probably the best performance boost to buck ratio.
Suggest double wrap with Thermowrap BEFORE installation. Adjust valves etc also since access is kaput. Double pipes and muffler are tough to do but desirable, also double wrap BEFORE installation. Some clearances about 3/32".
14 photos of my installation for what it is worth(have no idea who did the pipes, etc to share.)
