    Excellent information! I am trying to keep the intake and exhaust manifolds the same so these will be a bolt on application.... I will check out the heads when they are cut in half! (only one will be cut in half)

    Yes, see the previous notes on the castings... yes, water jackets!

    Can you tell me the valve springs/etc on your nailhead? I have been looking at BBC valve guides because they are longer than a SBC and they press in. I don't want the bronze guides, they will ware out prematurely.

    They are OE heads, and were highly massaged due to the poor castings. If you look close, one chamber where the spark plug is has been completely redone.
