Have you ever seen the heads Brodix offers for small block Fords, Chevys and Chryslers.  It has letter embossed into the ports to prohibit porting.  They all flow within one percent (if I remember right). 


I talked to them and they had never been approached to use the heads in drag racing, only in circle track racing.  He seemed intrigued by the possibility of using the head in that application.  I had done this for one of the heads up organizations but they did not want to pursue it.


Like you, I was looking for a way to participate without spending the savings account.


Anyway, I think any other head leaves the option of porting which may go undetected.
