modern tires on weinmann rims

i have two lovely sets of wheels i built myself in the late seventies. both with campagnolo NR hubs of course and butted spokes
one set is Weinmann Concave 700c, the other, 27" Weinman aluminum, conventional looking with reinforced but not separate ferrules.
i recently bought two sets of tires to replace the well oxidized originals: continental gatorskins.
one set of 27 1/4" for the 27 inch wheels and one set of 28 x 700c for the concave rims.
neither of the rims has a ridge to accomodate the wire bead on the new tires.
the gatorskins are rated to 120 lbs.
the original tires i used on the 27" were michelin with a 70 lb max and on the 700c Concaves, some other sort of japanese tire that i think would accomodate at least 80 lbs without problem.
i have not installed the tires yet and i am concerned whether the rims will hold the tires under the rated pressure.
the continental gatorskins have a printed warning: using only on rims with hooked rim.
should i be worried about the consequences?
can anyone help me here?
