280° adv,232°@.050", w/1.6 rocker lift .517" on 106° LSA. I was told the long block cam specs, and that the same Piston valve reliefs are not deepened, can't recall the cam specs at moment but it
had much more duration/lift but not as tight lobes, likely non issue as those reliefs are 2.2" and .286 deep, but Ill be checking it all,
