Highest flowing sbm heads?

Thanks, not many references me as genius :)
So, parts have to enterchange with your LA to be a small block. So I guess 289's, 350's, 302's, and all the such are not small blocks. Got it!
You truly are a genius. Please stay with me, the discussion is about small block Mopars. I know that's hard for your huge intellect to dumb it's self down enough to comprehend, but please try to keep up.
