Default bolt torque difference iron block & Aluminum Head

Ok, up popped a rattle in my Galaxie 289 water pump that has to be replaced. The engine had been converted to aluminum heads. The shop manual calls out 12-15 ft lbs, but that's for cast iron block and heads. Any idea what torque to use on the aluminum heads? Thanks Rob
