First time swapping edelbrock aluminum for 915 cast iron heads.

I do appreciate your and everyone else’s input. It has been invaluable on this website and without it I wouldn’t feel confident enough to tackle many of my jobs I have accomplished. I have to admit you are extremely knowledgeable in the compatibility of engine parts to create a superior performing combination. The problem for me is much of what you were saying was beyond my general knowledge and it made me second guess my performance part choices. But after I thought more about what you said I think I have come to understand a bit more. If the compression ratio is too low then you are leaving a lot of performance on the table and you also want your cam to develop maximal torque lower in the rpm power curve to be more responsive on the street where you may not easily be able to get above 6000rpm’s. Also as the compression goes up the cylinder pressure seems to rise if the chamber stays the same size. Higher cylinder pressure more powerful explosion greater power produced. I think I get it. But for me I have a couple factors to consider when talking compression ratio. I know there has to be a point where the compression is too high in an aluminum head to be practical to run on 92 or 93 octane. I don’t want pre-detonation and can’t afford to run a mix of race gas. Also even if the engine with 10.2 compression with the eddy heads leaves power on the table as long as I get a noticeable bump as compared to 9.8 to 1 iron heads I’m sure I’ll be happy. I would be unsure if I tried to run my motor with the aluminum eddy’s At 11.0 or higher compression. I think I would be setting myself up for problems. Especially with the ethanol they run in the gas in CT. Also I think there is more leeway in a slightly more radical cam when you run a 4 speed on the street vs an auto trans. What are your thoughts?
