When I get home, I'll measure my square port W2's. That looks way too small to be a square port W2.

Not wanting to hi-Jack the thread, but I'd like to see some casting numbers on that manifold.

They seemed a bit small to me as well.. But there is a ton of meat there. I dont think they intended them to be hogged out to far.. Notice the casting on the bottom showing where the standard bolt holes would have been.
