    Just want to know what the rpm range is for this heads, and if that come with flat tappet springs.  Thanks. 

    Asked by: Jmz87
    THis will depend on the camshaft used. This head is setup to use a hydraulic roller cam and is capable of 7000 rpm easily.

    Does the heads come with inserts for early 302 block using 7/16 studs? I have a 347 69 short block with a 575 lift hydraulic roller cam. Using hooker headers for a street performance mustang.
