question on 273 adjustable rocker arms?

[chargerbr549]

I know this is probably a dumb question but I just came accross a nice set of 273 adjustable rocker arms, can these be used on a big block set-up? I know the rocker shafts are different lengths but would the geometry be the same and would the pushrods clear everything with the 273 rocker arms on the big block shaft?

Not a dumb question and unfortunately, they aren't the same.
