Rotating exhaust valves

Is the valve closed, with spring pressure holding it closed? If so somethings wrong..

Rotators replaced with standard retainers & the stock spring could cause that...

Mostly Mopar used multi groove locks that allow the exhaust valves to rotate but don't use rotators... But there are some engines with rotators....

Anything the least bit performance oriented rotators get scrapped... On semi serious performance builds multi groove keepers get scrapped...
