440 Source Head Opinions?

20 or 30 hp more you can tell yourself that but it’s more like a 100 hp more with TF 240. Ive seen 760hp from a 4.15 stroke 383 with out of the box TFs. A hundred or more hp for $1200, thats a deal!

Isn't the TF 240 a CNC ported head? I'd sure hope it would flow more than a cast port head.
