Re: Keith Black HEMI heads
usually water heads .it all depends if they have been ported for a blower motor which most of them were. then other use would be poor performance. I suggest you have them flowed first to see if they would have too much for other uses.

Re: Keith Black HEMI heads
Thanks fred.
Do you know what valve size thay take, and do thay require any special rocker assemblys?

Re: Keith Black HEMI heads
many were only 2.25 intake and 1.90 exhaust but that is something that changed according to the combo. I have seen them with 2.35 and 2.40 intake and 2.00 exhaust. Consider the possibilty of going through a few sets of hands and they could be any size. rocker arms and stands are same as a conventional Hemi.Exhaust port might be raised "D" shaped and use a different header flange than factory style.
