If it were me I'd re-route the lines. But I've had good luck with the wraps too. Insulated, foil-covered tube type.
Agreed, when I rebuilt the engine for the '58 I bent up a new steel fuel line tucked in close to the block and experienced vapor lock after 10 miles of driving, much of it in stop and go traffic. Today's fuel boils at a relatively low temp, especially with ethanol blended fuel. A piece of heavy wall heater hose to insulate the line got me by until I could make a new line with different routing. The resulting air gap seemed to make all the difference.

Relocate the line away from the header...
