First time swapping edelbrock aluminum for 915 cast iron heads.

I get where your coming from AJ and agree, you know your chit. But you seem to be in a similar position that I am in over in here in UK, Start talking Tech (nowhere near as complex as you do), and most, not all, look at you with a blank expression, walk off or change the subject, frustrating to me as an ex racer, the money wasted on incompatible parts that I can see on some race cars is staggering, and sadly it seems to be more prevalent with the mopar guys. I've just learned to forget it all and just talk about how nice there car is lol.....there are a few exceptions, only 2 currently, 1 runs 8.80's in a '68 Cuda and the other 9.30's in a '64 Fury NA. There is 1 example I could give that is mind boggling but I won't bore you with all the details as is off topic anyways.
