intake, weld or glue

Since the cross ram small block intake is out of my price range, was thinking of modifying a single plane intake by lopping off everything up about 1 inch from the cyl head bolt flange and fabricating tubes to a plenum. Going to either two separate 4 barrels cross ram style or throttle bodies with injectors. The new adhesives have come a long way and can be ground on so might be easier than tig welding. Any thoughts? Also any one have a single plane intake with the water neck centered that they would unload cheap? center plenum does not have to be in good shape!
