So, does the angle rule get exempted for the SS/AH cars, or is that just for the "valve-cover fastener holes"? It's not entirely clear to me for those cars. Since it is one long, run-on sentence, the exemption would seem to apply to the whole sentence and SS/AH.

The intake manifold fastener hole lines have been deleted.
