Speedmaster heads for SBM

anybody see these on ebay. looks like an LA style casting with magnum chambers, and runners.

are these a deal for the bare head, or Junque?

So anybody else know anything about these good, bad, or otherwise, if the runners and chambers are nice, and the castings are good, wouldent a good gasket port match on the intake and exhaust side and a smoothing out of the runners without reshaping them work. I have dont this with mopar 2.2 ,turbo heads before just matched em to the intake and exhaust ports and smoothed out the runners and valve pockets.

Aluminum heads are definitely easier to do this with compared with iron heads. I wonder how much lighter than stock these are.
