42RH build recommendations

I put a 42RH behind my 5.9 magnum. Didn't do a total rebuild, but did put in the Alto red clutches and kolene steels, new front band,and I did the Transgo shift kit, some new gaskets and seals.
Running great, shifts nice, I have just the basic magnum build as well, airgap, Edelbrock 1406, stock cam so maybe a little less HP than yours.
The overdrive trans was one of the best things I've done to my car. So nice being able to cruise the highway at a nice low rpm.
