73 Duster build named Fred

We had a bigger cam we wanted to use but with his SPS flat top pistons they were very limited on valve to piston clearance. I bought this one used for 100.00 and it got hurt when a damn Comp cams roller lifter with 50 runs on them broke a tie-bar.
Now I’m starting to rethink my 727 build. Should I add a manual valve body and trans brake?
