The look more like stock runners that have been reworked and siamesed (look at the holes between the runners that are now opened as a single passage). Then the top side has been cut out and new material welded over the runners to open up the inside.

Yes, those look like the Siamesed AS&M Runners.

They do look like the Siamese AS&M they sold long ago.
Very rare, buy or hang on to them.

Id buy some real ones and do the same treatment if I was you. Youll only get so much through that small stock dia tubing.

Seen the ad for those myself, think it says they are custom, so I'd assume stock moded runners. Think they are siameases too far, was thinking bout modding my stock and rem reading it's better to keep it bout the same as slp or the as&m. Decided it's not worth my time becuase I'd still have small tubes.

Can't imagine anyone putting that much work into Stock runners.
They have flat plate mountings like the AS&M, not castings like the stock ones.
