All of Chryslers HP ratings are bogus, to some extent.
Either, they were trying to win popularity contests, or trying
to stay one step ahead of the government ratings.
An LA small block is a small block. The exceptions are the bore, stroke, and cam.
You can look at all the books you want, but a dyno is the only true measure of power.
Yes, there were some head differences, but you're asking about a 318.
