Here's a good read for anyone searching the yards. Changes by year reference.

I will have a pre 2000 to take apart, just might take a bit.
Lets just agree to disagree until I get some photos of Elvis holding a 1.88 valve magnum head.
RT heads were Mopar Performance and will have RT stamped on them. Never put on a RT from the factory. Aftermarket only.
Also its my understanding all factory Magnum heads 5.2 and 5.9 had 1.92 intake valves. Now I could be wrong on that but all the ones I have seen are 1.92.
So, whether I am right or wrong, lets assume i am wrong, that with either the .397" or .410" cams listed as 5.9 cams between 96-03 as biggest possible, would that not be an even better reason to change it to at least .450"? I think that was part of OP's original inquiry. The difference between the .397" cam and a .450" is huge, what the 5.9 begs for with stock heads. I would say .525" but didnt sound like OP wants to deal with springs. $.02
There was also a somewhat poorly documented "R/T appearance package" for non 5.9 Dakotas that included the R/T 17" wheels, fender flares and monochrome bumpers.
