RAIV with 1.5:1 rockers, no need to grind for pushrod clearance.
Fairly gentle ramps and .470” lift should be pretty easy on parts and have longevity. Heads with stock ports don’t really need more than .470” lift in this instance, the cubic inches will do the work.
It’ll be a fine street engine that you can drive anywhere with plenty of power.
