They should be easy to port with the valve angle and layout. I think the biggest downfall with the LA heads is the shared/dual ports and the pushrod pinch.
There's the little B Block option too for the :wtf: effect. Friend had a Fury with a 361. He would put a $20 bill on the dash board and tell the disbelievers to "grab it if you can" and then nail it. He didn't lose a 20 that I know of :lol:
