2.02's in 308's

I like what I see with 1.94 valves in the Mopar head. The Mopar porting templates and directions and templatesim about to dig back out here (very conservative porting to most, borderline ineffective to some) call for 2.02/1.60 valves with a specific valve job. FWIW, the results I’ve seen posted on ported 308s looked respectable, but I don’t remember the exact numbers. Quick question, though. My go to for machine work typically does 5/16 stems when doing LA Mopar heads. Any reason to stay with 11/32 stems or have you tested them?
