Okay I am la man but I have read quite a bit about the Magnums and I believe the RT head to be the same head that was on The late model 360 RT,pickups durangos etc now the crate motor 360 may have a 202 valve in them already. Wait to hear from the Magnum crowd.
Now there is a difference between the R/T Dakota/Durango heads and the Mopar R/T heads. The true R/T heads came with 2.02 valves. I believe the OP has these heads, not standard Magnum heads.
