I'm not looking to stuff the biggest cam in without running into issues, but am curious if anyone has an idea as to how much cam lift can bone stock 360 heads effectively handle/flow before it becomes overkill?? 1.88/1.60 valves..360 engine,9.2:1 compression
Max effective cam lift for 360 heads

The issue isn't "overkill" it is valve spring retainer to valve guide clearance. That said, the stock port is said to only stand at or a tick over .500 lift. You may run into retainer to guide interference issues before that.

I would think the overkill would be duration of the cam. at 9.2 to 1 too much duration would bleed off valuable cylinder pressure.
