1997 5.9L Magnum Roots Supercharging and Fitment

Yeah I was reading about that Pascamp, does anyone know of a set of better flowing aftermarket heads with both bolt patterns, or a set of heads with LA bolt style and magnum head gasket fitment? I am aware of a set of stock style magnum heads with both patterns drilled out, but I would rather not buy a set of heads just for a bolt pattern when I have brand new ones sitting on the block as it is.
