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

As I remember, those are 5/16" bolts so the bolt itself is the limiting factor. 12-15 ft. lbs. should be OK in aluminum as spark plugs in aluminum heads are torqued to around 20 ft. lbs.

Your are correct, it does not bolt to a head. I was looking at the head bolt holes for the P/S bracket. This rebuild is getting the better of me.
