all of them are like that.....both iron and alum.....if you get the right intake, you can put heater hoses to those ports.....and then just cut out the gaskets, if they don't have those holes...

Check my sig.....everything is cast iron (block and heads)...and i have an alum intake that has bosses to screw in hose adapters to run the heater hoses out....u do not have to use alum heads to get that...I am not!
