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
