They didn’t have a 308 casting but it did say 587? I think?

So as we keep learning here.. is it that if it doesn't have a roller cam in it 'even though it has the provisions' ..that it won't have the 308 or big push rod hole heads and can have any of the later standard LA heads instead. Good to know.
