7041242 uses #75 main jets with 45B primary rod, AV secondary rods and #7011957 power piston spring from factory.

Thanks for the observation on the float pin. I'll correct that condition. The jets, rods and hanger combo in the carb matches the Ram Air III which I though would be a better place to start at with my 413 ci displacement and XE276HR cam. I do have all the ones you mention though on hand.
