Does anyone know the dimensions of the SOHC head (relative to engine centerline would be nice)? I know the port spacing on the exhaust is an awkward 2 + 2'ish setup, not sure if it's narrower though, and actually doubt that you'd be able to make an effective spacer/ adapter to the SR manifold.
Easiest way to do a custom bottom mount setup for SR compatibility would be to just make a log manifold out of weld-els. At that point, though, you might as well just custom make everything.
