here's a good write up on the 1.92 R/T's. these guys seem pretty impressed with them after porting, must really wake em up.
i have them as well for my 408 build, however theyve got a good deal of porting done, titanium valves, and crower 1.7 RR's. now as far as price is concerned- try somewhere in the neighborhood of $450
however, i am confused... i feel like there were originally "R/T" heads on the R/T model dakotas that were only a a few cfm better than stock. and then mopar came out with revamped R/T heads. so, if this is the case, which are they?

The heads on Dakota R/Ts are no different than any other factory Magnum head.

Do not confuse them with aftermarket Mopar R/T heads.

the 141 R/T casting has 2.02 intake valves, but the 140 R/T casting still has 1.92 intake. they do flow about 10% better than stock and will clean up nicely with some porting. 2.02's AREN'T necessarily better, as 1.92's provide more velocity for lower RPM applications

was there any R/T model that had different heads? one member said they no longer sell the heads that the OP bought, when in fact, they do still sell the 1.92 and 2.02 R/T heads.
