For most automatic cars you'll need the cam/phase limiter, non-MDS lifters, a fresh set of head bolts and gaskets, and our street car and track tested PSI 1515 spring kit which includes the springs, Manley titanium retainers, and shims for 6.4L cars. For manual cars you can opt out of the lifters and head bolts/gaskets.
