Highest flowing sbm heads?

And if you read a word I said, you know better than to even post what you just posted. I said with cam swap and exhaust swap, they'll make 600 hp and that is the cheapest 600 hp with reliability you can about get. My opinion. :) And it was for the OP of this thread!
He doesn't know how to read. WE already established that.
What about Original Poster who wants the 350 CFM heads for some unknown combo unknown budget? Forget about him and go off on tangents new hemis are fast, 1,000 hp on stock blocks, no one looks at the late models when out cruising, late models faster then the classics, so and so is smart, so and so is full of it, chinese tubos, fast on a chevy budget, turtles ect ect ect.....
I made a post with a general outline of what's out there yet it was ignored. Maybe everyone has me on ignore LOL.
