Identification of M-6049-Z304DA Heads used on M-6007-D347SR Engines
Note that the M-6049-Z304DA Heads have been used on various Ford Racing Crate
Engines since 2006. Earlier heads from these street crate engines were not factory
installed on Ford Racing M-6007-D347SR Sealed Racing Engines. The heads used
to build all D347SR Sealed Racing engines can be identified by the size of the intake
port opening. ALL D347SR Sealed Racing Engines use a casting with the same
intake port dimensions with no exception.
Maximum Intake Port Opening
Width – 1.305”
