Four pedestals represent different catalog roles with one generic casting profile,not exact144973/4/5 machining. Inherited rocker bodies and valve positions stay; the revised support order is a reconstruction hypothesis,not a measured installed stack. Springs do not simulate preload or axial control; plain/end washer positions are unverified. Hollow shaft and blind locating recess do not reconstruct pressurized lubrication or oil drillings. Head receiver/stud engagement,threads,locking,wear,rocker handedness,contact/alignment,cam timing,valve lash,cover/head fit and tool room are unverified. No shim,external oil-feed kit,working articulation,strength,torque or safe/verified removal path is inferred. Whole-car inspection separation is illustrative; historical233-part engine core stays as fallback."
