another milling ? How much should I mill stock LS6 heads (243) to get around 11.0:1 CR with stock MLS gaskets? Would there be any sort of clearance issues with a 224 sized cam? Is 11.0:1 "safe" for a stock bottom end with no plans of blowers or nitrous in the future? If not what would be a better target CR for this set up? Thanks for your input!

If using a .052" gasket though, .014-.016" milled off should get you 11.0 CR

If I were you, I would get a .040 or so gasket and do not mill any further. The more you mill, the more you loose in flow.
Reducing gasket size is a better way because:
1- You keep more chamber and are able to flow more.
2- You tighten you quench and have less detonation problems which is one of the criterias in running higher SCR motors.
