    NOTES:

    1 The M-6564-B351 and -A50 bolt-on roller rocker arms will not clear the stamped rocker cover on standard 5.0L EFI engines. "Taller" valve covers, such as the production 5.0L EFI HO die-cast aluminum cover or Ford Racing chrome cover M-6582-D302, can be used if the baffle is modified in the RH cover. The M-6582-E302 polished aluminum valve cover will clear all rocker arms and stud girdles, but will not fit under the EFI manifold unless a 1" spacer M-9486-A53 is used between the upper and lower sections of the intake. M-6582-E302 will not fit 1994-95 Mustang or 1990-93 T-Bird.
    2 Rocker channels not included.
