Ported X head pics

I don't think there is, its a modified J casting a 915 casting. Looking at it they just filled the hole where the original pushrod would go, and drilled it over more so they could cast or port the intake port where the pushrod hole encroaches it. I may be totally wrong but that's what I see with the TA heads. If it were more than that it would have a whole unique casting number to itself right? Think in terms of a factory producing things on a budget.
