Highest flowing sbm heads?

And all of this because I stated in my opinion the Gen III hemi is the mopar small block that can get you on the plus side of 600 hp the cheapest and still be reliable. I wasn't even talking about the challengers/chargers they came in. Those are over 4,000 lbs. I was strictly talking about the topic the OP started in the thread.
And I gave you my opinion.....to each their own and since my cars are fast smart people will listen to me more than not, have a great day
