Best performing non offset Small block Mopar heads

how did they fail? Were there multiple motors put together that were underachievers? i remember the thread here and the motor made decent power up top and was a little light on torque but it could’ve been the intake and borderline low compression if i remember correctly. So the heads weren’t a magic bullet so to speak. So were there other engines too??
"Fail" may have been poor word choice. If I remember correctly they just didn't make the power that was expected of them. Been a couple years since reading that thread. Seems like there were 3 sets of heads involved. Hughes big mouth, Bloomers and maybe another. Might have only been the two heads.
