Might be cheaper than the Aluminum stuff available today. I'll get better flow and higher CR and no corrosion. For those of you who didn't race back in the 50's this was a common practice.
If you are going to do that, try filling the dome and using flat top pistons.
You can get enough compression to run alcohol then.
