DO THE NEW TRICK FLOW HEADS WORK ON THE 5.9 ENGINE ??---------Thanks , guys .

Yes, you’ll need the “Magnum” rockers & oil through pushrods as per TF. 1 head series that can use both rocker types for both block types.

A Magnum block *most likely* needs to be drilled for rocker oiling to use an LA style head. Although, there have been reports of some early Magnum blocks already having been drilled from the factory.

100% fact. This is what make the TF heads super attractive in addition to excellent flow specs.
