    Are these fully ported or are they the same as stock Boss 302 Heads.


    • The Ford Performance BOSS 302R Cylinder Head will be the same a s the production Boss 302 heads. These are not ported.

    Are these the heads to go with the 5.3 liter Boss block replacement for 4.6 3v motor?


    • No, the Ford Performance BOSS 302R Cylinder Head is designed for fitment with the Coyote 5.0l Blocks. The 5.3L Boss Block is based on the 4.6L engine and would not work with the BOSS 302R heads.

    Rocker Arms, Lash Adjusters? Will the stock rocker arms and lash adjusters work with these heads? Also...How about if I were to install Comp Stage 3 Cams?


    • yes they should work but you want to go better like the ones your asking about if you want to get good performance out of better heads

    Tune required? Seeing as the are CNC ported with more airflow I would think a tune would be required...If so, can BAMA add this to a tune or does it have to be custom tuned on a dyno?


    • DRH442 With these bigger heads and more aggressive cam grind. You would gain more from a custom dyno tune. Duke 7

    Do i need to purchase camshafts, rocker arms and lash adjusters if it is a direct bolt on? Will the OEM camshafts/ rocker arms and lash adjusters in the coyote work?


    • woodsy These heads do NOT come with camshafts, rocker arms, or lash adjusters. Duke 7
