(OP)
Why is cast steel not used for cylinder heads prone to cracking with cast iron?Most 1950-60 MG' cyl.heads I see have cracked. Is it a price question or a material one?

As for the use of iron, it has a lot of beneficial properties with regards to machinability and wear resistance (valve guides and seats).

Cast steel would be much easier to deal with as far as welding. It may add a bit more rejection during the casting process, again all about the costs.
Tugboat, yeah good old cracked D342 pistons, I have reused them many times, thems aluminum, and never had a problem with them.

Have a look at this video, it has a very good section on the casting of the block for a MTU 8000 series engine. (I only have experience with the 2000 and 4000 series).

And at the 7:30 time, he calls it "steel", I doubt that is an iron casting.
