My, aren't you charming. :violent1:
The quotes I posted were from a tech article on the Hughes Engines website. That is the reason I asked, and posted the quotes. I understand that the material does not effect static compression ratio.
More from Dave Hughes, "6. Power: Power depends on what you have to start with, or what else you plan to do to the engine. If you have low compression (9.5:1 or less) and are not going to change pistons or mill the heads to restore the cylinder pressure, save some money and go with the ported iron heads."
