If this helps you any, I'm running a "true" 10.4 compression in my 406 with "IRON" heads, My cranking pressure is 210-215, it runs great on pump 91 premium, The cam is not that big either, 224/234 @50 on a 112 LSA, Your cam will be your limiting factor when it comes to compression & pump gas, You CAN run 11.1 on pump gas with aluminum heads, its done all the time, You don't necessarily need a big can neither, just stay on one with a larger LSA, like a 112-114, If your going to run an aluminum head, shoot for a solid 10.5 compression & you will be fine.
