Trick Flow 440 heads, The Real Deal?

I will take the prototype one. Just PM me payment details and I can get you the cash and my address to ship it to. It is for an RB, correct?

Just wondering where we stand on this? I am still interested in your prototype if it fits an RB motor. If not I would be interested in commissioning you to do one that would work for a 440 block. Let me know please.
