For all you Buick fans that can not get ahold of all of those 1964 Buick aluminum heads and was wondering the weight difference, I hope this helps.

Aluminum has about 1/3 the density of cast iron, so aluminum bare heads and intake will weigh about 1/3 as much as cast iron.

Actually the aluminum heads are 17lbs lighter than the cast iron ones. Aluminum heads and intake instead of cast iron makes a difference of 50lbs on the nose. (300)

Hope what helps?

If you meant to include some actual weights here please do or I may delete this thread. There are some weights listed in other threads.

I know of a couple of guys running cast 300/340 heads. Bigger valves. I was told the pair of heads adds just under 40 pounds to the engine. Only ever held the aluminum 300 heads.
