390 w/open chamber heads

340sfastback,

Just out of curiosity, why would I mill the heads?? I know it will decrease the chamber volume but with all my "swept displacement" I'll get all the compression I need. There's no way I could cut them enough to get any quench because they are open chamber. But then again, I'm not an expert?? Let me know where I'm thinking wrong here as I am not a MOPAR expert.
I'm not disagreeing...just need more info, THANKS.
