Best iron cyl head?

the cam you´re using is pretty mild for a stroker engine....so i think you are not searching for the last hp......the rhs X-heads from IMM Engine (link posted above) should be absolutely ok for what you´re doing. I use these on my 408, got my first 11sec. time slip this summer (68´Valiant, full street trim). I know there´s more in it, the heads can support more. In my opinion it´s a nice package what Brian is doing there.

No, it's only for street use.
