Yes, they'll work on your L98.
You'll have to do 2 modifications, though.
1) remove the pushrod guideplates, because your motor has self-aligning rockers on it
2) You'll have to elongate the center intake bolt holes on your intake base because the aluminum 'vette heads use the "old" style bolt angles (all the same) rather than the newer (center ones canted less).
