It actually sounds more like a glitch with the game itself, though maybe he is doing something wrong.
Let's see... to piss off Heck you need the following: A) One person (Albatross or SIE) to be ready to be your handler in the final mission. B) To have a negative standing with Heck. Usually by using aggressive responsive (I think.), not going to him first in Taipei and by not deleting him from that computer. I believe that's all you need to do, though I guess a full Dossier would help.
Edit: As for Youth Trumps Experience, I beleive another thread found out that a big factor is that you have to use mostly suave responses for everything up until you meet Marburg.
