Cams for 318's

I know this is venturing into a different topic, but seeing as head choice is important for choosing a cam, I think it's relevant.

Is the #2843675 casting a higher compression head? It's from the pre-smog 318 la's. It lack the heart chamber and swirl ports, but I have read where successful builds have been done with it it, the Comp xe-268H and keeping the stock converter. That's larger than I think I would like to go for a cam, but are those heads a viable option for raising SCR with milling or any modifications?
